A pediatric or childhood cataract refers to any cloudiness or opacity (whiteness) in the normally clear lens of a child’s eye. A cataract can affect a very small part of the lens or involve the entire lens.
What causes pediatric cataracts?
Cataracts in babies may be caused by abnormal development of the lens before birth. By interfering with the light ray path to the retina (back part of the eye), cataracts in children can cause abnormal vision development and may result in permanent loss of vision if pediatric cataract surgery is not performed.
How are pediatric cataracts treated?
Infantile and childhood cataracts are commonly treated with pediatric cataract surgery. Cataracts that are small and/or off-center in the lens may not need to be removed because your child’s vision can develop normally, even with the cataract. Larger cataracts or those causing major visual loss should be removed, usually via pediatric cataract surgery, as soon as it is safely possible to do so.
