Cogan’s Dystrophy refers to a condition of an eye that affects the outmost layer of the cornea, called the corneal epithelium. Here, the term ‘dystrophy’ indicates an inherited eye disease. Cogan’s Dystrophy, also known as Epithelium Basement Membrace Dystrophy (EBMD) or Map Dot Fingerprint Dystrophy produces patterns just like that of fingerprint smudge within the cornea. It can occur in people over 30 years of age, and worsens away over time. Some of the common signs and symptoms of Cogan’s Dystrophy are light sensitivity, glare, blurred vision, fluctuating vision, and mild to extreme irritation and pain especially during morning time.
