Dear Hognose,
I read your Eye Doctors report and you appear to have what is a common problem that we diabetics experience and is really nothing to get yourself overly worried about. It would seem that your diabetes has resulted in a slight leakage in the blood vessels of your retina in both of your eyes which is something that's easily treatable using a lazer.
The procedure is quite straight forward and you probably won't feel a thing whilst it takes place, your only sensation being the tiny flashes of light that are used to seal up the leaking blood vessels within the retina. of your eye(s).
Sometime they decide to do each eye on different days, but it's more likely as things aren't so bad, that they will do both your eyes at the one sitting, and after it's all over (which is usually well within a fraction of a hour) you'll wonder why you were ever so worried in the first instant.
Please let us know how you get on - And best wishes.
