Is there anything i can do to slow and stop retina thinning?

I don’t know. This is a question that you should ask your Ophthalmologist. Since you are getting older, it might just be an affect of getting older. Continue to have regular eye exams.

no. But try to keep retina healthy with wearing sunglasses, no smoking, and healthy diet. Ask your ophthalmologist if ok to take eye vitamins called AREDS2.
