ABSTRACT

Of the myriad reasons for visits to an ophthalmologist, one of the most common maladies afflicting patients is Dry Eye Disease (DED), which can cause mild discomfort in the early stages and endstage ocular surface damage in its more severe forms. Dry eye is a problem of utmost importance, more in the developed rather than developing nations. Various aspects of the manifestation, including the tear osmolarity, ocular surface homeostasis and the role of ocular surface epithelial stem cells in maintaining the ocular surface homeostasis have been discussed. The objective tests to assess and grade dry eye have been noted. A systematic approach to the affected eye and the patient has also been outlined. The major categories of medications used along with the methods of delivery are specified in this review. A systematic approach in understanding the type and grade of Dry Eye Disease is mandatory for good clinical response. Along with clinical management the doctor should also stress on environmental changes that exaggerates dryness.
