For 3 months I have been suffering from strange visual disturbances. I am 26 yrs old and otherwise ok. My eye problems started with an increased amount of floaters and I was told I had PVD. From then on, I started experiencing strong afterimages, after everything I barely looked at (positive and negative). Then I started seeing light phenomena and visual snow/static, worse at night and in the morning. I also see light rays projected from cars, lamps etc. when I blink. When I try to sleep and close my eyes, I start seeing starnge, not formed hallucinations (like looking at a lava lamp) and often when I wake up I see a big black circle which disappears with a few blinks of the eye. Light seems to be a big factor, the afterimages are strongest in the morning when I wake up and visual static is strongest in the dark. I also notice that my visual fields are pulsing with my heart beat. I have had MRI and eye exams by ophtalmologist and neuro-oftalmologists including ERG and VEP and nothing has been found. I have no head-aches and have never used any illegal/recreational drugs. What could be the cause of my problems? Am I going blind? I suffer from nearsightedness, my glasses are about -4. This is awful, I cannot drive or watch tv anymore. My doctors tell me to see a shrink, but I am not anxious, stressed or depressed, any more than anybody would be given the circumstances.
