Meesmann epithelial corneal dystrophy is a genetic eye disorder that affects the cornea, the clear front part of the eye. It is characterized by the presence of small, clear cysts in the epithelial layer of the cornea, which can lead to symptoms such as blurred vision, light sensitivity, and discomfort. This condition is usually inherited in an autosomal dominant pattern, meaning only one copy of the mutated gene from an affected parent can cause the disorder. The condition typically manifests in childhood or early adulthood, but many individuals may remain asymptomatic for years. Diagnosis is made through a comprehensive eye examination, often using a slit lamp to visualize the cysts. While there is no cure, treatment options may include lubricating eye drops or, in more severe cases, surgical intervention to improve vision and comfort.
