Cataracts can form in newborns or small children, not just adults and the elderly. In children, cataracts can form for many reasons and we have to investigate the possibility that they have a metabollic disease or another general systemic congenital problem, that may be connected to congenital cataracts. Traumatic cataracts may also exist in childhood, particularly in children who get a blow to the eye when they are small. However, congenital cataracts appear at birth, they may be dense or not so dense, and cause amblyopia or lazy eye if not treated. It's essential to see an ophthalmologist who will determine when surgery might be necessary based whether your child's visual development is interfered with or not.
