I do scleral buckle surgery every week and it, really, is nothing to be afraid of. It is very successful in treating many kinds of retinal detachments
That being said cryo treatment to a peripheral retinal tear is very successful. I would not worry that this treatment will fail. Could a new, unrelated tear occur? Of course. But I am sure that your retina doc examined your entire retina and if she would have noticed any spots that seemed likely to tear she would have treated them at the same time.
The vitamins in the AREDS study were noted to be useful in dry age related macular degeneration. There is absolutely no proof that they would be helpful in your situation. Personally and professionally I would advise you NOT to waste your money on any "eye vitamins", including those from the AREDS study.
There are no data to show that exercise -- other then Golden Gloves boxing perhaps -- causes or predisposes to retinal tears or detachments. Go ahead and continue to enjoy your Yoga.
I am glad to hear that your doctor suggest you see an ophthalmologist
promptly when you noticed the blood/floater in your eye. No that tear is taken care of and everything should be OK.
Regina, I know that this is pretty scary, especially given what you went through with your TIA but, from everything you have told me and everything we have discussed so far I truly believe you are getting excellent care and everything will be OK
Let me know if you have any other questions or concerns. It is a pleasure to assist you.
