I recently saw my regular ophthalmologist for a yearly check up. I thanked her over and over for referring me to the retinal surgeon. She was interested and pleased with the outcome of my vitrectomy. She even asked me what kinds of questions she might ask a patient that would help her understand that a deteriorating vitreous might be the cause of the visual complaints. I describe my symptoms as increasing over time, first one eye and then both, visual effects similar to looking at pond water through a microscope, multiple one celled creatures, some in clumps, constantly moving, and yes, sometimes scarily obscuring vision. Or another way of describing—wispy , gauzy bits of moving clouds, between me and what I’m trying to see. Good Luck
