Double vision has a multitude of causes. When double vision develops suddenly, it should be investigated thoroughly, to make certain that all treatable causes have been considered. Double vision can develop due to a stroke, or due to a brain tumor or mass, pressing on one of the nerves that controls eye movement. These problems can usually be detected on an MRI or CT Scan. If such a problem exists, the underlying cause must be addressed before dealing with the double vision.
Another cause of double vision in adults is "microvascular disease". A prime example of this is diabetes. When the blood supply to a nerve is blocked, the nerve may stop working. With respect to the eye, if the nerves that control eye movement stop working, muscle imbalance and double vision can result.
In diabetes, and other conditions, the small blood vessels within the body are damaged. The circulation can be permanently or temporarily blocked. Not uncommonly, the blood supply to the nerves that control eye movement will shut down, stunning the nerves and causing a problem with double vision. Often, the first few days of this problem are associated with pain around the eyes.
When diabetes, or other microvascular conditions cause double vision, the problem usually resolves on its own within 8 - 10 weeks. No treatment has been shown to speed up this process. If, however, the double vision relates to another condition, it may never improve.
Typically, we wait until six months after the onset of double vision before we consider surgical or optical corrections for the symptoms. Occasionally, putting prisms into one's glasses can alleviate some of the double vision. If not, surgery can be considered. When a stroke leaves an individual with paralyzed extraocular muscles, some degree of double vision may remain, despite intervention.
