Dry Eye Exam in Winter Park, FL

Typically, dry eye disease can be diagnosed through a comprehensive eye exam and a description of your symptoms. On some occasions, the eye doctor might decide to do a test that measures how quickly your tears evaporate from the surface of your eye.

By instilling a simple dye called fluorescein (much like food coloring) the doctor is able to watch and count how long it takes the tears to start to break up after they’ve asked you to hold your eyes open after a blink.

This is called TBUT or a Tear Break Up Time test. A low TBUT generally indicates a lipid (aka oil) deficiency in the tears resulting from oil glands in the eyelids not functioning properly. In another type of test, called a Schirmer test, a strip of filter paper is placed under the lid of the eye and you will be asked to close your eye for five minutes.

Following the test, the amount of moisture on the strip will be measured. Schirmer tests are performed less frequently than a TBUT test.
