I fell on 1/1/2013 & srained my neck, back & right hip and shortly after noticed a sudden loss of vision in my right eye. I have been to 4 ophpthamologists' & a nuero-ophthamologist who can not explain the reason and cannot correct the vision to 20/20. I do not know if I hit my head at the time as my memory is foggy as I was in extreme pain at the time& immediately went to ER. I am suffering memory loss. Can a neck injury cause vision loss? , Can a fall cause vision loss in one eye? Also, Can a fall cause cataracts? Both eyes have similair size cataracts but only the right eye has a change of vision? I had no sign of cataracts at my last eye exam.
