My son is now 25 years of age, height is about 5 8 and weight is arouund 55 Kg. He is suffering from retinal generation in both eyes. He is able to see from only right eye since his birth. We came to know this problem when he was 10 years old. We have started homeophathic medicine since there is no medicine in allophathic. Ater some time He had been to cataract operation in which total degeration has taken place in the left eye.He is woking in some reputed company. Especially in the night he is getting some difficuilty. We are checking regularly from reputed opthomologist in mumbai. If any medicine to improve or do not further degenerate the cells of the retina, please suggest. opthomologist has advised me to give anything orally by mouth but not put any thing in the eyes. please suggest.
