kanyd, my husband has Devic's Disease(NMO). He has 2 spinal lesions, one at the base of his neck, which makes it difficult and painful to use his hands. And one on his lower spinal cord, he is in a motorized wheelchair, he can't use his legs to stand on. He can only use them only to transfer on a transfer board to bed, car, shower,etc.He was diagnosed March 2016 with neck lesion diagnosed Dec. 2017 with lower back lesion. He is taking carbamazepine, prednizone, he does plasamaphersis every 6 weeks, and retuxin twice a year. But like you, his vision is not affected which makes me wonder bc his eye dr said his vision is perfect. Right now he is not getting worse but he's not getting better either. He says he feels like he might not be able to use his hands much longer. At first they thought he might have transverse myelitis. i wish you well. I'll update if he has any changes. Marie
