Warning Signs Of Cerebellar Degeneration

Diplopia

Diplopia, double vision, may occur in one or both eyes. It's considered very serious if it persists when both eyes are open. With that said, diplopia in one eye when the other is closed is still considered serious. There are multiple causes of double vision. In some cases, the condition is caused by the muscles in the eyes. If one eye has weakened muscles, the eyes won't move in sync. This can occur because of weakened connections from the brain to the nerves that control the muscles. The nerves themselves might cause diplopia if they have trouble carrying information from the brain to the eyes. The optic nerves also connect straight to the brain. If the brain isn't processing images properly, that can cause double vision as well.
