Aniridia is the absence of the iris usually involving both eyes. It can be congenital or caused by a penetrant injury. Isolated aniridia is a congenital disorder which is not limited to a defect in iris development but is a panocular condition with macular and optic nerve hypoplasia cataract and corneal changes. Vision may be severely compromised and the disorder is frequently associated with a number of ocular complications: nystagmus amblyopia buphthalmos and cataract.
