Recurrent corneal erosions and epithelial basement membrane dystrophy.

Epithelial basement membrane dystrophy, the most common hereditary anterior corneal dystrophy and considered a "category 1" dystrophy in some cases, encompasses microcystic dystrophy and other conditions affecting the epithelial basement membrane. The management of symptomatic epithelial basement membrane dystrophy includes alleviating blurred vision, treating recurrent corneal erosion, or both. Treatment of distorted vision may be as simple as prescribing lubricating drops and/or ointment, and posttrauma corneal erosion is often a limited problem that disappears over time and does not require laser or surgical treatment. This article describes treatment for more severe cases of corneal erosion, which includes mechanical debridement of the loosened epithelium.
