Patients with congenital cataracts experience punctate clouding of the lens, which usually does not get bigger if it is static, but if the disease progresses faster, patients can experience a bigger clouding of the lens, resulting in a loss of vision for the patient. Congenital lens clouding is called congenital cataract, because the fetal period by external factors such as physical, chemical, inflammation and other factors affecting the development of the crystalline lens, the crystal turbidity after birth, which is divided into total cataract, anterior polar cataract, punctate cataract, around the nucleus cataract and so on. In some patients, the condition is stable and the clouding usually does not increase. If the condition progresses significantly, the patient’s lens clouding can worsen. Anterior polar, punctate and corolla cataracts are usually static and have little effect on vision, so they generally do not require treatment. On the other hand, nuclear cataracts and total cataracts need to be treated surgically, usually before the age of 4 months and no later than 2 years old, so as to avoid amblyopia in the future. Patients with congenital cataracts are advised to seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
