Corneal Thickness is Reduced in Dry Eyes

Dry eye disease, is a multifactorial pathology that affects tears and ocular surface resulting in symptoms of discomfort and visual disturbance that injures the conjunctiva and corneal epithelium. Environmental factors often implicated in dry eye includes exposure to pollutants, UV radiation, ozone and use of preservative eye drops. These factors often cause dry eye which increase oxidative stress causing ocular surface inflammation where corneal epithelium usually gets injured. Here, various studies were reviewed that points to the affect of dry eye on corneal thickness and showing thinning of cornea among dry eyes associated with other factors. And these studies reported to have found reduced thickness in dry eyes and different studies reported decrease in corneal thickness in dry eye showing the relationship of corneal thickness present in dry eyes present with other factors including diabetes, menopause etc.
