Aniridia is defined as a partial or complete absence of the iris. Aniridia can be either congenital or acquired. Congenital aniridia is a rare disease that affects both eyes. It is autosomal dominant in the majority. Most of the other cases of congenital aniridia are sporadic. Sporadic aniridia may correlate with WAGR syndrome (Wilm tumor, aniridia, genitourinary anomalies, and mental. Aniridia is a rare, sight-threatening disorder that affects the cornea, iris, intraocular pressure, lens, fovea, and optic nerve. Individuals with aniridia characteristically have a variable degree of iris hypoplasia and foveal hypoplasia, which leads to nystagmus and impaired visual acuity (usually 20/100 - 20/200 BCVA) 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. Aniridia is an eye disorder where the iris (colored ring structure of the eye that forms the pupil) is malformed. In some cases, other structures of the eye are also poorly developed. The word aniridia implies that there is no iris, but in fact there is a small ring of iris tissue present which is variable in size
