If you have dry eye, your symptoms may include irritated, scratchy, dry, uncomfortable or red eyes, a burning sensation, excessive tearing, blurred vision, or a feeling of something foreign in your eyes. Excessive dry eyes may damage eye tissue, scar your cornea (the front covering of your eyes) and impair vision and make contact lens wear difficult.
Any condition that reduces the production, alters the composition or impedes the distribution of the preocular tear film (POTF) may cause a noticeable irritation to the structures of the front surface of the eye and a degradation of vision. These conditions are often related to problems with the structure or function of the eyelids, cornea, or conjunctiva. Depending upon the severity of symptoms, individuals may be limited in their ability to see clearly and comfortably and may be at increased risk of developing a secondary infection or chronic inflammation that may not respond to treatment.
The two most commonly encountered ocular surface disorders are tear film disorders and blepharitis. Additional subclassifications include those dry-eye states associated with systemic connective tissue disorders, specifically Sjogren syndrome (SS). With regard to lipid deficient tear-film disorders, the involvement of meibomian gland dysfunction (MGD) has been proposed.
An estimated one-fifth of visits to eye care practitioners are related to ocular complaints secondary to dry eye, and as many as 25 percents of American adults may be affected by dry eye or have dry eye symptoms. These statistics indicate a significant need for access to professional care.
We perform specific tests to assist in differentiating the various forms of tear film abnormalities and identifying potential treatment strategies. Careful clinical observation, accurate diagnosis, and appropriate intervention can eliminate or minimize the deleterious effects of ocular surface disorders on the quality of life.
