Hi all, My father is facing issue on his eyes. He is loosing his eyesight gradually. Around 8 year back when he went for check up, doctor referred him for aims (dell hi) and their doctor mentioned that no cure for this issue. And they have given suggestions to control diabetes (as he is a diabetic). He started some yoga and some ayuvadic medicine to cure this. But now seems issue increased and he is facing difficulties to recognise the face from 5-6 feet. Could some one please help to know if there is any new treatment available which can improve the eyesight in case of ratina issue. Thank you.
