due to chronic sinus infection, infection covered optic nerve in the left eye and shut down the signal to the brain, caused blindness. needed surgery: they scrapped infection off of optic nerves causing total blindness in both eyes in 2002, total blindness was for three years, then i started seeing shadows and shapes, now i'm visually impaired. so now the question is how to replenish the optic nerve because i have chronic pain all the time. is there any treatments available???? please respond to ***@****.
