  • Abstract
  • Look Inside

Aniridia is often associated, among others, with peripheral corneal opacity and vascularization of unknown etiology. We examined 5 patients with virtually total aniridia clinically and histologically with impression cytology. These patients com-prised 3 males aged 39, 46 and 68 years, and 2 females aged 23 and 43 years. Slitlamp examination showed epithelial and/or stromal opacification, and superficial vascularization in the peripheral cornea. Palisades of Vogt, which is normally located in the corneal limbus, were completely absent. Impression cytology showed numerous goblet cells in the cor-neal epithelium. These findings seemed to imply that corneal epithelial abnormalities in aniridia are secondary to depletion of stem cells in the corneal epithelium.
