Patient: Hello! Professor, the child went to the hospital for a detailed examination and the result is cataract + permanent vitreous hyperplasia, the baby is only 33 days old now, do I need surgery? Is it possible to do it. Is it possible at this age? I don’t think the surgery will be unbearable with general anesthesia, right? I would like to go to Beijing for the best treatment time. Thank you very much! Pang Lin, Strabismus and Pediatric Ophthalmology, Peking University First Hospital: The impact of permanent vitreous hyperplasia on visual development varies a lot depending on the location and degree of the disease, and it is possible that cataract surgery may still not improve vision, so it depends on the specific situation. If there is a chance to improve vision after surgery, the surgery should be done early. Many children here have been operated in 1~2 months, and some of them have achieved good results in long-term vision development. In China’s top hospitals, general anesthesia now has very little long-term impact on children, so don’t worry.
