Congenital cataracts do not usually cause retinal detachment. Congenital cataracts and retinal detachment are two different disorders that occur in different parts of the eye, and there is usually no relationship between the two. Congenital cataracts are caused by abnormalities in the development of the lens inside the fetal eye due to genetic factors, intrauterine infections, or exposure to toxic or radioactive substances during pregnancy. Treatment varies according to the severity of the condition. Mild congenital cataracts are observed and do not require intervention for the time being, while severe congenital cataracts need to be treated with surgery as soon as possible. Retinal detachment is the detachment of the retina from the wall of the eyeball, which is related to developmental abnormality, retinopathy of prematurity and other reasons, and needs to be diagnosed through fundoscopy and ultrasound examination, and usually requires surgical treatment to reset the retina. Patients need to go to the ophthalmology department of the hospital as soon as possible after a detailed examination to confirm the diagnosis, and then the doctor will formulate a scientific and reasonable treatment plan to eliminate the symptoms.
