Dryness? Itching?

These symptoms may be more than simply irritating. They may be indicative of Dry Eye Disease, where your lacrimal glands stop producing enough tears or where the tears that are produced may evaporate too quickly.

Dry Eye Disease symptoms can often be eliminated by treating the cause.

3 Common Screening Tests

Tear Break-Up Time (TBUT)

TBUT gives us an indication of how stable your tear film is. Because the tear film in people with Dry Eye Disease is unstable, it will break up faster than normal and cause the eye surface to feel uncomfortable. In a TBUT test, a diagnostic dye is added to the eye and the tear film is observed while the patient avoids blinking. TBUT is the time it takes between a blink and the development of tiny dry spots in the stained tear film. The longer it takes, the more stable the tear film. If your tear film breaks up in less than 10 seconds, you may have Dry Eye Disease.

Diagnostic Dye and Lissamine Green Staining

These tests use a yellow or green dye along with a blue or white light respectively to detect damage that may have occurred to your eye. A piece of blotting paper containing the dye is touched to the surface of the eye. The patient is asked to blink, which will spread the dye on the tear film. A light is then directed at the eye. Any problems on the surface of the cornea will be stained by the dye and appear green under the blue or white light.

Meibomian Gland Expression

This test allows us to see if your oil-secreting meibomian glands within the eyelids are clogged. These oils help prevent tear evaporation.
