For the past five years I have been slowly losing my vision. I have had a couple sets of mri's, a lumbar puncture, and a good bit of blood work done and all of the results have been negative for anything that may have caused it. It seems to be that heat, excessively strenuous physical work, and a lack of sleepo make my vision worse for a short period, but it's gradually getting worse and I am afraid I may be legally blind within a year or so. I'm just wondering if there's anyone else out there who has had these kinds of problems and their doctor hasn't been able to figure it out.View Thread
