Hi. I'm online and happy to answer your question today.
From what you have posted, it sounds like your grandfather either had damage to the area of his brain that is involved in vision or, possibly, damage to his retina from a vascular issue.
Going just on what you have posted I am very sorry to say that it doesn't seem like anything can be done to restore his vision.
If you could give me more information, or even better yet, scan and upload copies of his medical notes, I would be able to give you more specific information on what has happened to your Granfather's vision and what, if anything , can be done.
Does this answer your question to your satisfaction?
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me. If you have another question on this or a related issue feel free to fire away. And please let me know if the rating system gives you any troubles. Thanks in advance, Dr. Rick
Good Morning. Welcome to chat. I was just addressing your question.
Hello Rick, Thank you very much for support. I really feel not good to hear that but I also do not have all documents yet to show you as well. I am trying to get them and as soon as I get them I will send it to You.
Thank you again.
