About
Congenital aniridia is a pan-ocular genetic disease characterized by a partial or complete absence of the iris, hence its name. The prevalence ranges from 1 / 40,000 to 1 / 96,000 births, but it may be underestimated. This condition combines several types of eye damage and could associate systemic manifestations, with a variable phenotype and genotype.
This study aims to identify eye and systemic manifestations in congenital aniridia and to determine the patients' knowledge of their own disease through a survey prepared by ophthalmologists from the Ophthalmology Department of Necker-Enfants Malades Hospital, reference center in France for this pathology. The patient fills it out only once.

Congenital aniridia is a pan-ocular genetic characterized by partial or complete absence of the iris, hence its name. The prevalence ranges from 1 / 40,000 to 1 / 96,000 births, but it may be underestimated. This condition combines several types of eye damage :
Congenital aniridia can also be associated with several severe systemic manifestations, including syndromic aniridia (WAGR syndrome and Gillespie syndrome).
The major gene responsible for autosomal dominant forms of congenital aniridia is PAIRED BOX GENE 6 (PAX6) (MIM#607108) with over 500 pathogenic variants reported to date.
Congenital aniridia is therefore a rare, pan-ocular disease associating systemic manifestations, with a variable phenotype and genotype.
This study aims to identify eye and systemic manifestations in congenital aniridia and to determine the patients' knowledge of their own disease through a survey prepared by ophthalmologists from the Ophthalmology Department of Necker-Enfants Malades Hospital, reference center in France for this pathology.
