Hi dear..
Please understand , no one will be able to comment anything on this ...as we do not know anything about the patient ...what surgeries, vision, what paralysis eye or general , and we are not seeing the patient.!
So best is to manage with local doctors and discuss with them ..control
diabetes, BP and other systemic issues ...
If at all, you have a report by the Ophthalmologist ..and u kind of want a second opinion ..u can post that paper ..then may be something , we can help you .
Take care .
