Unilateral corneal endothelial dystrophy and anterior keratoconus.

PURPOSE To describe a case of keratoconus and Fuchs' corneal endothelial dystrophy in the left eye with no corneal disease in the right eye. METHODS A 64-year-old woman presented with visual impairment in her left eye; computer-assisted topographic analysis and specular microscopy were performed in both eyes and left cornea was histopathologically examined. RESULTS Keratoconus was diagnosed by slit-lamp examination, keratometry, and computer-assisted topographic analysis. Corneal endothelial dystrophy was diagnosed on the basis of clinical examination and specular microscopy. Histopathologic examination revealed a stromal degeneration typical of keratoconus and a non-guttae form of endothelial dystrophy. CONCLUSIONS This is a rare case of unilateral corneal endothelial dystrophy and keratoconus.
