Myasthenia Gravis Support Group
Myasthenia gravis (MG) is a neuromuscular disease leading to fluctuating muscle weakness and fatiguability. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Although myasthenia gravis may affect any voluntary muscle, muscles that control eye and eyelid movement, facial expression, and...

As one of my eye lids drooped, I learned to close one eye that way and do away with patching an eye. I practiced until I could close either one and alternate using the eyes.
Mestinon never got rid of DV, although it made the two images somewhat closer together -- but that didn't really help.
From my start of DV, it took me several months on prednisone to get rid of it.
I never was quite sure of why prednisone took so long, but did speculate on two possibilities -- once we have a buildup of a lot of antibodies, it takes time for them to disappear; or the muscle receptors were damaged and took a while to grow back and a third was that the prednisone was just slow to act.
I think the doublevision was maybe the most troubling part of my time with MG as it was almost always there and annoying. It was my first clear symptom of MG and when it finally stopped, sort of gradually improving, it marked a great day in my treatment. Breathing was, of course a worse issue, but seeing normally gave me hope treatment was working.
I did find that when I was driving with DV, and kept one eye closed, when I approached an intersection or other place where two eyes were needed, I could tilt my head way back and look out with my eyes to the bottom and the DV resolved as long as my head was way back. And so I drove with one eye shut until the worrisome places then drove with my head back seeing normally for a little while.
Good Luck Kenneth. Hope your site is back to normal soon.
