Dry Eye

Dry eye occurs when your eyes produce either too few tears or a poor quality of tears. Symptoms may include pain, light sensitivity, a gritty sensation, a feeling like something is in the eye, itching, redness, and blurry vision. Dry eye can cause changes in vision that affect your ability to perform daily tasks such as reading and driving. Factors that may contribute to the development of dry eye include excessive time spent looking at computer and smart phone screens, age, hormones, medication, and certain medical conditions.

The flow of tears is necessary to moisten and lubricate the eye’s surface. When the eye isn’t getting enough lubrication, it sends a message to the brain that triggers more lubrication, but sometimes those tears are mostly water and don’t coat the eye surface well. Tears are made of water for moisture, oils for lubrication, and mucus that helps the tears spread properly. The normal production of these components creates a three-layer “tear film” that protects the surface, helps prevent infection, and maintains comfort. A poor-quality tear film can cause dry eye.

There are two general types of dry eye: aqueous-deficient (a lack of production of the “watery” component of tears) and evaporative (a lack of production of the oily component of tears). Glands in the eyelids known as meibomian glands produce the oily portion of the tears, therefore any lack of production is termed meibomian gland dysfunction (MGD).

Because the condition tends to worsen over time, early diagnosis and prompt treatment of dry eye and MGD can prevent damage that leads to severe discomfort and vision problems later in life. Dry eye can also affect the success of surgical eye procedures, so the condition should be addressed before any type of vision correction procedure is attempted. Although dry eye cannot be cured, it is possible to relieve symptoms with eye drops and ointments, medication, or plugging some of the tear ducts to slow the drainage of tears once they collect on the eye’s surface. Certain new treatments can provide significant relief.
