If it damages the nerves that control your eyes, you may see double. Multiple sclerosis can affect nerves anywhere in your brain or spinal cord.Nerves. They carry information from your brain to your eyes. Problems with them can lead to double vision: It can cause vertical diplopia, where one image is on top of the other. Graves' disease, a thyroid condition that affects eye muscles.Early signs include double vision and drooping eyelids. Myasthenia gravis, an autoimmune illness that stops nerves from telling your muscles what to do.A problem with the nerves that control them.When you look in a direction controlled by the weak muscle, you see double. If a muscle in one eye is weak, it won't move in sync with the other eye. They control eye movement and keep your eyes aligned with each other. Cataracts can be worse in one eye than the other and can grow at different rates between your 2 eyes.ĭouble vision when both eyes are open is called binocular diplopia. Lens. This sits behind your pupil, the opening in your eye, and helps focus light onto your retina in the back of your eye.Ĭataracts are the most common lens problem. Keratoconus, when your cornea becomes cone-shaped.It could be that your cornea in that eye is uneven. If your double vision goes away when you cover one eye but remains when you switch and cover the other eye, you might have cornea damage in the eye that’s seeing double. It might involve your:Ĭornea. This is the clear window into your eye. To understand how diplopia can happen, it helps to know the parts of your eye and how they work together.ĭouble vision in only one eye is called monocular diplopia. Generally, double vision in both eyes is more serious than if you have it in just one. You might have diplopia in one eye or both. Non-invasive non-surgicial Vision Therapy with or without corrective lenses is the best course of treatment in order to gain single vision AND improved vision (binocular or two-eyed vision and depth perception).Diplopia is when you see two images of the same thing. The brain controls the eye muscles and eye muscle surgery (i.e., strabismus surgery) does not directly change or improve the brain's “control system” and its signals to the eye msucles. Double Vision and Strabismus SurgeryĮye muscle surgery or strabismus surgery is not the recommended best course of treatment for getting rid of double vision and gaining binocular vision (stereopsis). In those cases, brain surgery could be part of the recommended treatment plan. The exception to this statement is cases in which the double vision is caused by a brain tumor. Vision is spread across so many areas of the brain and is so diffuse in function that this means that the best treatment for double vision would rarely, if ever, be brain surgery. Approximately one third of the human brain is involved in the processing of vision. Vision, including 3D binocular vision, uses many areas of the brain simultaneously.
