Map Dot Fingerprint Dystrophy
By far it is the most common type of corneal dystrophy. It has got many alternative names like epithelial basement membrane dystrophy, Cogan’s dystrophy and anterior basement membrane dystrophy. The name it has got is due to its slit lamp like appearance. Common symptoms include eye pain, blurred vision excessive tearing and light sensitivity. The abnormal growth of epithelial basement membrane causes this disease. The abnormal growth in turn causes the epithelial erosions and there remains a small gap between the outer-most layer and the cornea. Diagnosis includes eye and vision test. Anterior corneal punctures and corneal scraping are some methods for treatment.
