1. Yes there is some risk but it declines rapidly as time passes. Best prevention see your ophthalmologists regularily.
2. Yes but again as time passes the risk becomes very small.
3. I suspect not since its usually due to scarring of the retina and underlying choroid. As your surgeons.
4. Same answer as #3.
There is always hope and there is much research. Perhaps someday the answers will be different.
