Thank you so much for your advice.Could you please elborate more on treatement that he may require as this was possibly a gradual loss of sight over a period of last 4-5 years which my father didn't notice as it was totally painless.
Woul realy appreciate your quick response.
Dear Dr. PG;
Thak Your advice. Just now I had a word with him( my Father) and he told me that He has not lost it completely. He can still make out the shape but it's very blurr. Any hopes of recovering it back from this stage.
