Have you ever gotten up from the table after enjoying a meal and noticed that things appeared fuzzy or blurry? If so, you may have experienced a temporary spike in blood sugar that affected your eyes.
If your vision is often blurred after meals, you should schedule a visit to your optometrist and general practitioner to rule out diabetes and other conditions.
The Link Between Blood Sugar and Vision
Diabetes is characterized by excessively high blood sugar levels. In some people it causes food to be digested faster than usual, leading to rapid spikes in blood sugar. Elevated blood sugar can lead to fluid to build up in the eyes, resulting in blurry vision.
The eye’s natural crystalline lens and cornea are responsible for focusing light onto the retina for clear vision. The lens changes its shape to accommodate focusing on near or far objects. In some cases, when the eye swells due to excess fluid resulting from the high blood sugar, it temporarily doesn’t focus light with the same accuracy.
Foods that are high in sugar and other carbohydrates are most likely to cause blood sugar to spike. Some examples include:
White rice and pasta
Most breakfast cereals
Potatoes in all forms
Sugary sodas and beverages
Candies and baked goods
Other Possible Causes of Temporary Blurred Vision
Temporary eyesight changes don’t always mean diabetes. Intermittent blurred vision can be caused by other problems or conditions, including:
Pink eye (conjunctivitis)
Many of these conditions will also present with symptoms other than blurred vision, so be sure to be open with your optometrist if you experience any unusual visual symptoms.
If you notice blurred vision only following a high-carb meal, it may be worth tracking your meals and symptoms to try and find a pattern. This information will be valuable for your optometrist and other health care professionals.

How often do I need an eye exam?
The American Optometric Association recommends that adults have their eyes checked by an optometrist every 1-2 years. For high risk patients, patients who wear glasses or contact lenses, or those over the age of 65, annual eye exams are recommended. Certain conditions like diabetes may make it necessary to visit your optometrist more often.
Does being diabetic make a person more likely to experience vision loss?
Diabetes can negatively impact your eyes in more ways than one, but preventing vision loss and blindness is becoming easier with new technology and treatments. Having undiagnosed diabetic retinopathy puts a person at a much greater risk of going blind. If you or a loved one has been diagnosed with diabetes, be sure to schedule regular diabetic eye exams including retinal scans, to significantly reduce the chances of experiencing permanent vision loss.
Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.
Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness:
Age-related macular degeneration (AMD)
The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.
How Obesity Contributes to Eye Disease
A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list.
Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss.
The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.
Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair!
Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.
A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease
Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.
An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases.
We Can Help Keep Your Eyes Healthy in Winter Park
While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. Ward can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.
If you have any questions or concerns regarding your vision or eye health, don’t hesitate to call Aloma Eye Associates — we’re here for you.
Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it’s important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor.
But First, What Is Diabetes?
Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn’t produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.
Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.
What’s the Link Between Vision and Diabetes?
Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels.
If you start to notice blurry vision, make an appointment with Dr. Ward as soon as possible.
The 3 Ways Diabetes Impacts Vision
While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective.
Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss.
Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.
Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.
Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.
The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact Aloma Eye Associates in Winter Park to set up your eye doctor’s appointment today.
Your eyes aren’t just the windows to your soul — they can also reveal valuable information about your general health beyond whether you need glasses, including: diabetes, heart disease, and even cancer. It is not unusual for people to come in for an eye exam just to check their eyesight and then have certain health issues or predispositions picked up by the optometrist.
Eye Exams and Your Health
Eye examinations can help doctors detect general health conditions early enough to intervene. Advanced screenings enable eye doctors to better predict cardiovascular incidents like stroke, and possibly detect signs of mental changes such as Alzheimer’s. Read below to learn how eye exams can unveil a whole lot more than just eye health.
Brain Cancer & Stroke
Because of the similarities between the blood vessels in the eye and brain, an eye doctor can occasionally detect an issue taking place in the brain by examining the blood vessels in the eyes. If swelling or shadows in the eye is observed, it may indicate a serious condition in the brain, like a tumor, or clots that might result in a stroke.
Diabetes can cause damage to the blood vessels in the retina at the back of the eye, resulting in Diabetic Retinopathy (DR) and Diabetic Macular Edema (DME). If an optometrist detects leaky blood vessels in the eye, the patient would be advised to see a doctor to help control their blood sugar. Changes are gradual, and they start before visual symptoms are noticed. The earlier diabetic eye disease is managed, the better the chances are of preserving eyesight.
High blood pressure, characterized by having too much pressure in the blood vessels, can be detected during an eye exam, sometimes even before it’s diagnosed by your regular doctor. The damaged blood vessels lead to swelling, hemorrhages, and leaking — all of which can be observed in the eyes. According to the CDC, hypertension “the silent killer” affects nearly 1 in 3 adults, and up to a whopping 20% of those don’t even know they have it. So early detection at an eye doctor’s evaluation can be truly life-saving.
Eye exams can also detect a buildup of cholesterol. High cholesterol is among the easiest conditions to spot during a complete eye exam, as the cholesterol deposits manifest on the front of the eye, appearing as a thin, gray rim around the cornea. It can also be detected in the retina by assessing artery and vein patterns.
These deposits may indicate the current or future development of Retinal Blood Vessel Occlusion, a condition where blockages restrict blood flow to the back of the eye, causing temporary or permanent vision loss.
In some cases, heart conditions associated with a buildup of plaque in the carotid artery in the heart can also lead to deposits that clog the ocular arteries in the eye. If an optometrist detects such changes to the vascular structure at the back of the eye, he or she will typically recommend going to a specialist.
Multiple Sclerosis (MS)
Sudden vision loss may be attributed to Multiple Sclerosis (MS). While the optometrist can recognize signs indicating the presence of MS, such as the color and appearance of the optic nerve, such cases will be referred for further testing to confirm the diagnosis.
Thyroid disease can make itself apparent through the eyes in several ways. The thyroid gland controls the hormones that regulate tear production so some thyroid disorders can cause dry eye disease. Additionally, overactive thyroid (hyperthyroidism) can make the extraocular muscles enlarge and stiffen, causing bulging eyes — an indicator of Graves’ disease.
Systemic conditions that are associated with inflammation in the body can have an inflammatory effect on the eyes. Uveitis, for example, causes eye inflammation, redness, and blurred vision, and tends to occur in people with lupus, rheumatoid arthritis, and other autoimmune diseases.
Breast cancer, leukemia, and other metastatic cancers are occasionally discovered during an eye evaluation. In addition to brain cancer mentioned above, melanoma and basal cell carcinoma (skin cancer) can be detected, and eye doctors can also diagnose lymphoma and other eye tumors. Eye exams save lives.
What the Future Holds
Recent studies show that a non-invasive and precise imaging device called Octa (optical coherence tomography angiography) can signal the presence of eye changes associated with Alzheimer’s disease. Because the retina is in many ways an extension of the brain, the altered blood vessels at the back of the eye offer a glimpse into the changes taking place within the brain.
Parkinson’s Disease can often be misdiagnosed as its early symptoms are characteristic of other conditions. Research has shown that subtle eye tremors, an early Parkinson’s marker, could be detectable using advanced eye exam technology. One day soon, practitioners may send patients to an eye doctor to test for this and other diseases.
Your Eye Doctor’s Appointment Could Change Your Life
So the next time you visit Dr. Ward at Aloma Eye Associates in Winter Park, remember that a comprehensive eye exam can do more than determine your eyeglasses or contacts prescription. Dr. Ward can evaluate your eyes for existing or potential health issues, and communicate them to your primary care physician for the best possible care. By knowing that you’re at risk for a certain disease, you can take precautions early on and manage the condition as needed. After all, an ounce of prevention is worth a pound of cure.
Diabetes Awareness Month – Learn about Diabetic Eye Health in Winter Park
November is Diabetes Awareness Month, a time to learn more about diabetes of all types – type 1, type 2, and gestational diabetes.
Everyone knows the word “diabetes,” but can you define the condition? Diabetes is a disease characterized by higher than normal glucose levels in your blood. Blood glucose is what fuels your body, and it comes from the food you eat. When blood sugar flows through your bloodstream, insulin is needed to help it enter your body cells so it can be used for energy. However, if you have diabetes, your body may make insufficient insulin or not be able to use the insulin properly. As a result, all that sugar stays circulation in your blood – unable to be converted into energy.
Diabetes can be managed very well through diet, exercise, and taking medication. Without controlling diabetes by keeping blood sugar levels within the parameters recommended by your doctor, the high blood sugar can damage many organs – including your eyes. Staying healthy by following your personalized diabetes management plan and making sure to visit your eye doctor for regular eye exams, you can pave your path to good vision and eye health!
Diabetic eye health & diabetic eye disease
To state the facts – diabetes-related eye disease can lead to vision loss, but if you have diabetes, you can minimize your risk of developing diabetic eye disease. Taking charge of your health and visiting our Winter Park eye doctor for regular eye exams can help prevent these diseases from developing.
Diabetic eye disease comprises several ocular conditions:
Diabetic retinopathy – occurs when the small blood vessels in your retina bleed and leak
Macular edema – swelling that occurs along with retinopathy; it happens when the retinal blood vessels in the macula (central region of the retina) leak and lead to inflammation
Cataracts – a clouding of the lens in the eye, which can cause blurry vision
Glaucoma – increased intraocular pressure, which damages the optic nerve and can cause loss of peripheral vision
Diabetes eye exams
With regular check-ups by our Winter Park eye doctor, you can help prevent eye problems or keep the problems minor. One mistake that many people with diabetes make is to assume that a diabetes eye exam is only necessary if they notice any symptoms. This couldn’t be further from the truth! A comprehensive eye exam is the only reliable way to detect several eye conditions that can cause vision loss, such as diabetic retinopathy, glaucoma, and cataracts. Early detection of these problems can make the difference between effective, successful treatment and damage to your vision. During your dilated eye exam, the eye doctor will use high-powered magnification to inspect the inner tissues of your eye thoroughly, checking the retina for signs of diabetic retinopathy and checking the optic nerve for any damage.
According to the American Diabetes Association (ADA) guidelines:
People with type 1 diabetes should have their first diabetic eye exam within the first five years
People with type 2 diabetes should visit their eye doctor for the first diabetic eye exam immediately after diagnosis. Type 2 diabetes can remain undetected for years, and vision damage can occur during this time.
Women with gestational diabetes should have an eye exam during the first trimester of pregnancy
After the first diabetic eye exam at Winter Park, our eye doctor advises all adults with diabetes to visit yearly for a comprehensive dilated eye exam.
At Aloma Eye Associates, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 407-671-3100 or book an appointment online to see one of our Winter Park eye doctors.
Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.
Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.
"In 2014 alone, eye doctors found diabetes-related manifestation in 240,000 patients who were not aware they had diabetes, leading to a prompt diagnosis and care, which minimizes the risk of complications," says AOA President Andrea P. Thau, O.D.
What is Diabetes?
Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.
How Does Diabetes Affect The Eyes?
Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.
In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.
The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.
As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.
The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.
The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:
Blurred or fluctuating vision or vision loss
Floaters (dark spots or strings that appear to float in your visual field)
Color vision loss
There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.
A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.
Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.
Diabetic Macular Edema (DME)
Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.
Treatment for Diabetic Retinopathy and Diabetic Macular Edema
While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.
Prevent Vision Loss from Diabetes
The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.

November 14th is World Diabetes Day. This year, the theme of World Diabetes Day is women and diabetes – our right to a healthy future. The goal of this campaign is to promote awareness of the importance of equal and affordable access for all women, whether they are at risk or already living with diabetes, to the treatments, medications, technology, education and information they need to prevent diabetes and to obtain the best possible outcome of the disease.
Here are some facts about women and diabetes around the World:
199 million – the number of women living with diabetes to date.
313 million – the projected statistic for the year 2040.
2.1 million – the number of female deaths due to diabetes per year.
9 – diabetes is the ninth leading cause of death in women on a global scale.
60 million – which is 2 out of 5 diabetic women, are of reproductive age, which increases the risk of early miscarriage, vision loss and having malformed babies.
10 – women with type 2 diabetes are ten times more likely to develop coronary heart disease.
Much of these incidences of diabetes occur in women lacking access to proper medical care, education, physical activity and information they need to prevent and manage the disease. If more efforts and monies were put toward improving this situation, these numbers could drop significantly.
Pregnant women with hyperglycemia and gestational diabetes are also a major cause of concern. Limited access to screening tests, pre-pregnancy planning services, education and medical care could also improve the outcome of both the mother and the baby in these cases. The majority of instances of gestational diabetes occur in women from low and middle-income countries or households with limited access to maternal care.
Here are some additional facts about diabetes and pregnancy:
1 out of 7 – the number of births worldwide affected by gestational diabetes.
1 out of 2 – the number of women with gestational diabetes that develop type 2 diabetes within 5-10 years after giving birth.
1 out of 2 – the number of cases of gestational diabetes that are found in women under 30 years of age.
Diabetes and Your Eyes
Diabetes damages many systems in your body including your eyes and vision. Most individuals with diabetes will eventually develop some extent of retinopathy or eye disease due to the consistently high levels of glucose in the blood which damage the blood vessels in the eye. Diabetic retinopathy can be a devastating disease that can leave you with permanent vision loss or blindness. It is a leading cause of blindness worldwide. Diabetes also speeds up the formation of cataracts and other ocular diseases which can lead to further vision loss and complications.
Women who have been diagnosed with diabetes prior to becoming pregnant have to be especially careful during pregnancy. It is much more difficult to regulate blood sugars during pregnancy, and more rapid progression of diabetic retinopathy can occur if one is not careful. Keeping track of diet and exercise, and taking medications as directed, can prevent or delay the impact of diabetes on the eyes.
In addition to poorly managed blood sugar levels, additional factors that contribute to developing diabetic retinopathy are high blood pressure, high cholesterol, Hispanic or Native American descent, smoking, pregnancy, and the length of time you have the disease. The condition can be managed with regular eye exams in combination with steps to control blood sugar levels.
It’s important to note that diabetes sometimes causes symptoms of vision fluctuation (good days and bad days with vision or focusing) but many times the damage is asymptomatic in its early stages. This is why it is essential to have regular checkups even when you have no pain or vision symptoms.
If you or someone you know has diabetes, regular eye exams are essential to monitor and prevent vision loss. Stay informed and spread awareness about this challenging condition. You can help be part of the change to improve the lives of women and people all over the world that suffer from diabetes and the serious complications that come with it.
Diabetes is a growing health crisis in North America as an estimated 29 million Americans and 3.4 million Canadians are currently living with the disease. Chances are it affects you or someone you know. November has been dedicated as a time to spread awareness about the disease, its risk factors and the effects it has on your body, your daily life and the lives of your loved ones.
Diabetes and Your Eyes
Diabetes is a systemic disease that causes fluctuations in glucose (blood sugar) levels which can affect blood vessels throughout the body including those in your eyes and visual system. People with diabetes are at higher risk for blindness than the general population, however with regular eye exams and proper care, most of the complications are minor and treatable.
Minor changes in glucose levels could result in complications such as blurred or double vision, floaters or even visual field loss. These conditions are usually quite treatable. Diabetics are also at greater risk for developing eye diseases such as glaucoma (40% increase risk) and cataracts (60% increased risk). With early detection, both of these conditions can be treated and the majority of vision restored.
Diabetic eye disease often has NO noticeable symptoms or pain, so comprehensive eye exams that include dilating the pupils are essential to detect signs of diabetes. Online vision assessments will not detect diabetic eye disease.
The condition that is the most concerning risk of diabetes is called diabetic retinopathy which can lead to blindness if not diagnosed and treated.
What You Need to Know About Diabetic Retinopathy
Diabetic retinopathy occurs when the tiny blood vessels or capillaries in the back of the eye develop weakened vessel walls. If not treated, the vessels leak fluid and become blocked. This can progress to hemorrhages in the retina, and over time the eye does not receive enough oxygen and nutrients. As a result, new fine blood vessels start to grow. These proliferating vessels leak and can cause further bleeding, scarring and potentially lead to blindness. A special zone in the central retina called the macula is especially susceptible to diabetes. Diabetic macular edema (when fluid seeps into the macula) can cause permanent vision loss if not promptly detected.
There are treatments for stopping the progression of the disease such as laser therapy or intraocular injections, although once damage to vision has occurred, it is often permanent. This is why the condition must be diagnosed and treated early on.
All diabetics should have a regular comprehensive eye exam to catch any early signs of diabetic retinopathy or other vision threatening conditions. Because risk factors vary, speak to your eye doctor about how often you should have an exam. Risk factors for diabetic retinopathy include:
Length of time living with diabetes
Uncontrolled blood sugar levels
High blood pressure
Although blindness from diabetes is preventable it is still a leading cause of blindness among working-age adults. If you or someone you know has the disease, make sure that proper eye care is a priority.
It’s true. Diabetics have a higher risk of blindness than those without the disease. That fact coupled with the superior prognosis of early intervention, makes it easy to understand why optometrists and doctors say routine eye care is absolutely essential. Below, we’ll discuss what your eye doctor is looking for during a diabetic eye exam.
As the incidence of diabetes increases, it is important to spread awareness about the risks and proper preventative care for diabetes patients. November is Diabetes Awareness month, so read on!
Diabetics are at greater risk of for a number of eye problems.
Diabetic retinopathy is the term used for the disorders associated with diabetes that cause progressive damage to the retina. The longer a patient has had diabetes, the more likely it is that he will develop these conditions which can be very serious, vision-threatening complications.
There are two types of retinopathy: nonproliferative and proliferative.
Nonproliferative retinopathy, which is the most common form, is when capillaries at the back of the eye become weakened and may start to leak blood and fluids. Nonproliferative retinopathy, which often has no symptoms, can be characterized as mild, moderate or severe, depending on how many blood vessels are affected and becoming blocked. This type of retinopathy usually doesn’t require treatment and doesn’t cause vision loss, unless the leaking fluid ends up in the macula where the eye focuses – a condition called macular edema. If this happens, vision can be blurred and even lost so preventative treatment is essential.
Proliferative retinopathy is much more severe. This is when so much damage is done to the blood vessels that they begin to close off. New blood vessels begin to grow in the retina as a response to this deterioration. The new and weak vessels can leak blood, impairing vision, or can form scar tissue which can distort the retina or cause a retinal detachment.
Proliferative retinopathy requires urgent referral to an ophthalmologist for treatment. While it usually takes years to develop, some instances of proliferative retinopathy can occur within weeks or months if blood sugars are not well-controlled. Pregnancy can also accelerate proliferative retinopathy in known diabetics. Yet if detected early, treatment can be done successfully.
Like high blood pressure, there are often no warning symptoms until advanced stages of diabetes. It is best to get checked each year by an optometrist. If you experience any changes in your vision such as spots in vision, flashes of light, blurred or double vision (rarely pain), make an appointment with your eye doctor immediately. Treatments do exists for retinopathy and many of them are successful in repairing damage and sometimes even restoring vision.
Cataracts are a clouding of the lens of the eye which blocks light from entering and impairs vision. While cataracts are a fairly common and treatable condition, people with diabetes are 60% more likely to develop the condition and often get them at a younger age. Those with the condition also may experience vision fluctuation which occurs from sugar levels affecting the lens of the eye. Cataracts often progress faster in diabetics as well. In serious cases of cataracts, a surgical procedure is done to remove the natural lens of the eye which can sometimes cause complications in diabetic patients that may already have symptoms of other conditions such as diabetic retinopathy.
Glaucoma is a serious condition where pressure builds up in the eye causing damage to the retina and optic nerve and eventually if left untreated, blindness. Diabetics are 40% more likely to develop glaucoma and the risk increases with age and the amount of time the individual has had diabetes. There are treatments for glaucoma including medications and surgery but early detection and treatment are essential to prevent permanent vision loss. Glaucoma is often called the “silent thief of sight” because vision loss often doesn’t occur until significant damage is done. Therefore, yearly eye exams are essential.
Diabetics may experience reduced sensitivity in their cornea. This means that contact lens wearers that are diabetics should be more cautious, as they develop higher tolerance if the lens irritates the eyes and may be at greater risk of infection.
Eye Muscle Disturbance:
More advanced diabetes cases can show restriction of eye muscle movement due to nerve palsy.
For diabetics, the key to early detection and treatment – and therefore preserving your vision – is to have your eye health monitored on a regular basis. Get your eyes examined every year by an optometrist and if you experience any changes in your vision such as spots, floaters, blurred vision or pain, make an appointment with your eye doctor immediately.
If you or a loved one suffers from diabetes, awareness of the threat of vision loss due to diabetic eye disease should be a top priority. Don’t wait until it is too late to learn about the risks.
Here are eight true and false questions about diabetic eye disease to test your knowledge. If you have any questions, contact your eye care professional to find out more.
1) Diabetic Retinopathy is the only eye and vision risk associated with diabetes.
FALSE: People with diabetes have a higher risk of not only losing sight through diabetic retinopathy, but also a greater chance of developing other eye diseases such as cataracts and glaucoma. People with diabetes are 40% more likely to develop glaucoma and this number increases with age and the amount of time the individual has diabetes. Diabetics are also 60% more likely to develop cataracts and at an earlier age than those without diabetes. Additionally, during the advanced stages of diabetes, people can also lose corneal sensitivity and develop double vision from eye muscle palsies.
2) Diabetic retinopathy can cause blindness.
True: In fact, diabetes is the leading cause of blindness in adults age 20 to 74.
3) With proper treatment, diabetic eye disease is reversible.
FALSE: Although early detection and timely treatment can greatly reduce the chances of vision loss from diabetic eye disease, without prompt and preventative treatment measures, diabetic eye disease can result in permanent vision loss and even blindness. Currently, there is no cure that reverses lost eyesight from diabetic retinopathy; however, there are a variety of low vision aids that can improve quality of life for those with vision loss.
4) People who have good control of their diabetes and their blood glucose levels are not at high risk for diabetic eye disease.
FALSE: While studies do show that proper management of blood sugar levels in diabetics can slow the onset and progression of diabetic retinopathy, there is a still a higher risk of developing diabetic eye disease. Age and length of the disease can be factors for eye diseases such as glaucoma and cataracts. The risk of diabetic retinopathy can be influenced by factors such as blood sugar control, blood pressure levels, how long the person has had diabetes and genetics.
5) You can always prevent diabetic eye disease by paying attention to the early warning signs
FALSE: Oftentimes there aren’t any early warning signs of diabetic eye disease and vision loss only starts to become apparent when the disease is already at an advanced and irreversible stage.
6) A yearly, dilated eye exam can help prevent vision loss through diabetic eye disease.
TRUE: Diabetics should get a dilated eye exam at least once a year. Since diabetic eye disease often has no symptoms, routine eye exams are critical for early detection and treatment. Everyone with diabetes should get an eye examination through dilated pupils every year, because it can reduce the risk of blindness from diabetic eye disease by up to 95%.
7) Both type 1 and type 2 diabetes are at risk of developing diabetic eye disease.
TRUE: Everyone with diabetes – even gestational diabetes – is at risk and should have a yearly eye exam. In fact, 40% to 45% of those diagnosed with diabetes have some stage of diabetic retinopathy.
8) Smoking increases the risk of diabetic eye disease.
TRUE: In addition to getting regular eye exams, stop smoking, partake in daily physical activity, maintain a healthy weight and control blood sugar, blood pressure and cholesterol: they all help reduce the risks of eye disease.
Whatever your score on the quiz above, the most important take-away is that if you have diabetes, even if you aren’t having any symptoms of vision loss: make an appointment for a comprehensive, dilated eye exam every year. It could save your sight.
