I have occasional floaters that are evidently residue from when I had a bleeder on the edge of my retina a few years ago. My optometrist saw something he wanted checked. The next day I was at a retinal specialist. The took pictures of my eye, and the opinion that day was that the bleeder was not active. I was given an appointment for a month later so they could compare pictures and see if there was any activity. A month later they took more pictures, and 20 minutes later I had a laser zapping my eye, burning the bleeder. No more problems. I now go to an optometrist with the equipment to take the pictures of my eye, in an office with a retinal specialist (and the appropriate laser), but I've had no more problems. I used to be able to see the burned spot if I tried real hard. I now can barely see it with my eye closed. Caught it before it did any real damage.
