Congenital cataract is a condition where the lens in the eye is cloudy from birth. The term "congenital" refers to the fact that the condition is present at birth. Synonyms for the word "congenital cataract" include: infantile cataract, childhood cataract, developmental cataract, juvenile cataract, and pediatric cataract. These terms all describe the same condition, but may be used to describe the age at which the cataract develops. Congenital cataracts can occur in one or both eyes and may be inherited or caused by environmental factors such as infections or trauma. Early detection and treatment are critical for the best possible visual outcome.
