How is someone's vision affected by Aniridia?
How much someone's vision is affected by aniridia depends on several factors. Lacking an iris does not cause blindness by itself, but rather depends on the extent of the disease and the exact parts of the eye affected. Predicting if a baby will lose vision in the future is difficult because ocular complications may occur in the future from the disease that may reduce someone's functional vision. Some of the symptoms of aniridia such as nystagmus (repetitive involuntary eye movements) or recurrent glaucoma and cataract can reduce someone's visual functioning.
