What Causes Double Vision?

Multiple Sclerosis

Multiple sclerosis, which can cause an affected individual to experience double vision, is an autoimmune disorder where an individual's immune system abnormally attacks the healthy tissues of the central nervous system or the optic nerves, brain, and spinal cord. It is known to be a very debilitating disease because it causes the patient's central nervous system nerves to malfunction when sending and receiving signals to and from the rest of the body. The optic nerve is the main nerve responsible for the transmission of visual information impulses from the individual's retina to the vision center of the brain. Even though it is technically a part of the eye, the optic nerve is also part of an individual's central nervous system. Multiple sclerosis causes the immune system to attack the protective myelin sheath that covers the nerves and allows for the smooth transmission of electrical impulses. Because the optic nerve is a part of the central nervous system and is made out of nerve or ganglionic cells, multiple sclerosis can disrupt the normal transmission of visual images through the optic nerve to the vision center of the brain. This disruption causes a number of vision abnormalities, including double vision.
