Meesmann Corneal Dystrophy Associated With Epithelial Basement Membrane and Posterior Polymorphous Corneal Dystrophies

Abstract

To report a rare case of bilateral and symmetric Meesmann corneal dystrophy concurrent with bilateral epithelial basement membrane dystrophy and bilateral but asymmetric posterior polymorphous corneal dystrophy in a patient of Armenian origin. Complete ophthalmologic examination was performed on a 6-year-old boy from Armenia who was diagnosed with bilateral symmetric Meesmann corneal dystrophy combined with bilateral epithelial basement membrane dystrophy and bilateral but asymmetric posterior polymorphous corneal dystrophy. This case was observed and treated for 24 years. On slit-lamp biomicroscopy, the patient showed bilateral multiple intraepithelial cystic lesions, bilateral irregularly shaped grayish-white opacities in the superficial corneal epithelium, and bilateral but asymmetric transparent vesicles surrounded by gray halos at the level of the Descemet membrane and the endothelium. This case is reported because of the unusual occurrence of Meesmann corneal dystrophy with other corneal dystrophies.
