Although the most apparent clinical finding in aniridia is the absence of iris tissue, additional ocular structures are often affected. Mutations of the Pax 6 gene, which is important for eye development, have been identified in families with members affected by aniridia. Poor vision in aniridic eyes may be the result of macular hypoplasia, nystagmus, amblyopia, cataracts, glaucoma, and corneal disease, termed aniridic keratopathy. Advances in surgical techniques have improved management of some of the visually disabling manifestations of aniridia, but aniridic keratopathy remains a significant source of visual loss. We have conducted a large, retrospective study of patients with aniridia to gain information about the natural course of aniridic keratopathy. In this paper, we report the results of our study, as well as findings reported in the literature. Penetrating keratoplasty alone has not been a successful treatment for severe stromal scarring, as it does not treat the underlying epithelial causes of corneal disease. However, it has been successful in corneas that have achieved stable epithelium following limbal stem cell transplantation.
