The expensive rubber band I have around my right eye is to reattach a
detached retna. I was very lucky.
One of the symptoms of detached retna is floaters. The best way I can
describe what I had was that I was seeing gnats. It was like the
little black gnats that hang around ripe fruit. I was seening them fly
around sporadically but they weren't there. If you see gnats get your
ass to the doctor without delay. My eyesight was saved by a nurse who
knew what it was and wouldn't let me wait a day, if she had had a
pistol she would have pulled it on me and put me in the trunk of the
car to get me to the surgeon.
