What is (are) Meesmann corneal dystrophy ?
Meesmann corneal dystrophy is a rare genetic condition affecting the epithelial membrane of the cornea. A slit-lamp examination of the cornea shows diffuse clusters of tiny round cysts in the epithelial membrane.  Over time these cysts can rupture and cause erosions. The erosions may result in light sensitivity, redness, and pain. Vision remains good in most, but not all, cases. Meesmann corneal dystrophy can be caused by mutations in the KRT3 or KRT12 gene. It is inherited in an autosomal dominant fashion.
