Open full text 0 citations

Abstract

Congenital aniridia is caused by a mutation in the PAX6 gene [1] and is characterized by partial or complete absence of iris tissue. Apart from the hypoplasia of iris tissue, other ocular features such as foveal hypoplasia, nystagmus, aniridia-related keratopathy, Peters anomaly, Axenfeld-Rieger anomaly and glaucoma are seen in these eyes [1,2]. Cases have been reported with persistent pupillary membranes [3] and iris strands [4].
