Aniridia is a rare congenital condition characterized by the underdevelopment or even absence of the eye's iris. This usually occurs in both eyes. It is associated with poor development of the retina at the back of the eye resulting in visual loss.
Treatment
The iris functions to restrict the amount of light entering the eye, so if it is absent, most individuals with aniridia are sensitive to bright outdoor light and their eyes may need protecting. This can be done with tinted
glasses, or with a
contact lens which has an artificial iris painted onto it.
