I have Hemiplegic migraines. Attacks only occur on my left side. With each attack I lose vision in my left eye. Although this is common for most FHM suffers, my eyesight in the left eye has not fully been restored. I have seen opthmologists as well as neuro opthmologists and they cannot explain the permanent and rapid loss of eyesight in my left eye. I have had numerous MRI's and CAT scan's looking for tumors, optic nerve damage, etc. Everything looks normal and healthy. It is not a "refractive" problem that can be fixed with eyeglasses or lasic surgery (which I have had and had 20/20 vision from 3 years ago.) Nonetheless, my eyes are tested every few months and my left eye loses more vision after these attacks and does not return when all other symptoms subside. My neurologist and team of doctors have said they have never seen this before. Is there anybody out there going through something similar? Any response would be greatly appreciated!
