Cataracts and Aniridia
Cataracts occur in approximately 50-85% of people with aniridia. Cataracts may be present at birth, or can develop at any time in life. The risk for developing cataracts increases with age.
A cataract is a clouding in the lens of the eye. The lens of the eye acts like the lens of a camera, focusing light on the retina. The retina changes the light into nerve signals. These signals travel along the optic nerve to the brain, and the brain interprets them as images. If the lens is not clear, light passing through it will be scattered instead of focused and vision will be blurry.
