Patients with congenital cataracts who do not have any symptoms can be closely monitored for the time being without intervention. Congenital cataracts are mainly caused by genetic and environmental factors, such as gene mutation, intrauterine infection during mother’s pregnancy, and exposure to toxic and radioactive substances during mother’s pregnancy, etc. Whether or not symptoms occur is related to the condition. Mild congenital cataract is only a dot-like clouding inside the crystalline lens. It is usually asymptomatic, does not affect vision, and does not require treatment; close observation of changes in the condition will suffice. In some cases, the clouding of the lens may worsen with age, and if it affects vision, it can be treated surgically. Severe congenital cataracts will affect visual development and can form amblyopia. Once detected, surgery should be carried out as soon as possible, and after the surgery, amblyopia training should be provided to improve the children’s visual acuity. Even if there are no symptoms, congenital cataracts should be reviewed regularly and treated with surgery if necessary to avoid further aggravation.
