Fortunately Marg has never had sleep problems related to her damaged optic nerves. Her spasms have made up for that in this area

The low vision ophthalmologist has told her that the damage to her optic nerves likely occurred years ago from the MS but the other undamaged nerves have been able to compensate for quite some time. But as usually is the case with MS, the disease progression gets to a point where your nerves can no longer compensate and the problems begin.

The doc told her that there is likely no recovery of the nerves in this situation and she will have this problem for the rest of her life!
