Keratopathy in Congenital Aniridia
The Ocular Surface, 2003Although 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.

Aniridia: A Comparative Overview
American Orthoptic Journal, 2014Aniridia is linked to a mutation of the PAX6 gene, which results in panocular anomalies. A set of common secondary pathologies associated with aniridia is recognized. Much of the literature on aniridia focuses on genetic factors of the disorder and associated abnormalities, both ocular and nonocular. The field of research on the prevalence of pathology

The Ocular Surface in Aniridia
2015In aniridia, ocular surface alterations arise after several years, in distinction to congenital anomalies such as absence of the iris and cataract. In patients with aniridia, the cornea is transparent at birth and gradually loses transparency from 18 to 20 years of age due to the formation of a superficial vascular pannus determined by limbal stem cell

Aniridia and congenital ptosis
Plastic and Reconstructive Surgery, 1975Congential ptosis associated with aniridia was found in 3 patients from 2 pedigrees. Nonsurgical aphakia, a condition not previously reported in association with aniridia, was also found in one case. The association of aniridia and congenital ptosis is suggested as evidence for the common mesodermal etiology of both anomalies.

The Indian Journal of Pediatrics, 2003
Aniridia (absence of iris) is a congenital, bilateral, uncommon panocular disorder. Whereas the occurrence of aniridia in the general population is 1:50000, it is present in about 1 in 70 patients with Wilm's tumor. This aniridia is sporadic and Wilm's tumor in these cases presents at an unusually early age.

Aniridia in a Thoroughbred horse
Equine Veterinary Journal, 1990Summary Aniridia presents with very characteristic typical signs and has been reported in man (Newell and Ernest 1974), calves (Saunders and Fincher 1951) and horses (Ericksson 1955; Joyce 1983). This case report records aniridia in a Thoroughbred.
