In general, the difference between traumatic cataracts and congenital cataracts mainly lies in the different etiologic factors and the specific clinical symptoms. Cataract refers to the congenital or acquired factors, resulting in the lens protein degeneration and clouding, including lens transparency or color change. Patients with traumatic cataracts are caused by injuries to the lens, such as blunt contusion of the eye, penetrating injuries, and blast injuries. Congenital cataracts, on the other hand, are caused by congenital genetic or developmental disorders and are usually present after birth. The main clinical manifestations of traumatic cataract are decreased visual acuity, decreased contrast sensitivity, double vision, etc. It can also be accompanied by trauma-induced eye pain. The clinical manifestations of congenital cataract are white pupil, photophobia, visual impairment, etc. The affected children can also have amblyopia and other manifestations. It is recommended to strengthen the daily protection of the eyes, avoid trauma, and actively check the treatment during pregnancy to prevent the child from suffering from congenital cataract. Patients with cataracts should seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
