It might be difficult to discern between parasitic worms and a parasitic fungi infection in the eyes unless, of course, you've seen/felt worms move. Someone else had mentioned stringy things from the eyes -- this could be fungi or worms or a possible mixed infection. I remember that someone on the Parasite Forum (Sapphire?) drew a picture and what she saw looked like an actual worm. To me, it looked like a definite worm with details. I'm sure, "floaters" have been ruled out as a cause for your problem.
Perhaps when Apxr has some time he could lend his comments as well.
