I don't have double vision but have major eye problems and pain. Were talking 50 apts and 10 eye specialists plus neurologists etc. It is hard to find a doctor who connects the eyes with rsd but it seems common that people with rsd have eye problems. I have heard others mention double vision. Some videos I have seen for ketamine infusions etc the patient is wearing sunglasses cause of eye problems.
For myself I hope one day if my rsd limb pain gets better that what ever treatment is used for that will also help the eyes.
