Re: vitreous detachment
Just to give you some odds, it may be 15% that the retina tears with a vitreous detachment, and out of that, only about 1% detaches, it's not a common thing, they just check it to make SURE because it is something that COULD happen. A tear would be there that they could zap with a lazer. A tear that is not fixed "could" detach the retina, so I wouldn't be too worried about it. The most common time for any problems resulting from the vitreous detachment is when it first happens, and the danger of a detachment is reduced thereafter.
