- Diabetes. The nerves that control eye movement may be damaged. If the diabetes is controlled (treated effectively) the damaged nerves usually repair themselves and the problem resolves.
- Myasthenia Gravis - this is an autoimmune neuromuscular disorder in which the muscles become fatigued and exhausted.
- MS (multiple sclerosis) - the central nervous system (CNS) is attacked by the person's own immune system. That is why MS is known as an auto-immune disease. The CNS includes the brain, spinal cord and optic nerves.
- An aneurysm - occurs when part of a blood vessel (artery) or cardiac chamber swells, - either the blood vessel is damaged or there is a weakness in the wall of the blood vessel. As blood pressure builds up it balloons out at its weakest point. The swelling can be quite small or very large - when large it tends to extend along the blood vessel. As the aneurysm grows there is a greater risk of rupture - this can lead to severe hemorrhage, and other complications, including sudden death. If the arteries in the brain bulge there is a risk of developing double vision.
- A blood clot - if this develops behind the eye, eye movement may become restricted.
- A stroke - a condition where a blood clot or ruptured artery or blood vessel interrupts blood flow to an area of the brain. A lack of oxygen and glucose (sugar) flowing to the brain leads to the death of brain cells and brain damage, often resulting in impairment in speech, vision, movement, and memory.
- Cancer - a tumor in or behind the eye may distort the image the eye produces. A brain tumor may also be a cause of double vision.
- Injury - head injuries can sometimes result in damage to the muscles in the orbit (eye socket), or the nerves that control eye-movement muscles, both of which can result in double vision.
“Internal organs of the refined Qi into the eyes and whom Jing(Essence) ...... Jing disappear cause Diplopia, Diplopia is the simultaneous perception of two images of a single object . "Under normal circumstances, the blood of the Essence of the internal organs, Liu Fu Clean Yang Qi, are into the eyes and head . Orifices get Qi and Essence, then you can see clearly. “
I mean patients who have diplopia see double vision is because their eyes can not get enough Qi and Essence.
According my experience, most Diplopia patients are 40s to 50s. Most of them have to use their eyes a lot and have pressure in working, such as IT programers and teachers. Their work hours are pretty long and they have to focus on small screen or books, therefore their eyes need plenty Qi and blood to support. When their Qi is blocked, eyes will be easy suffered. Acupuncture is able to help Diplopia. It can help patients to deal with the block and to manage Qi and blood into eyes. Most of my patients can feel different in two or three times treatments. I had a patient who was a teacher retired earlier than normal age because of Diplopia. He told me he went to many doctors but no one could help him. He could not drive and lecture on the podium because of double vision, Diplopia came really frequently and stayed long time it made him dizzy and headache. After two times treatments, he felt much better. He still had double vision but it did not come so frequently. Double vision came and went so quick usually only few seconds compared before double vision had to stay minutes even an hour, it was really huge different. About 10 times treatments, he told me double vision never came again. Acupuncture is a really treatment for Double Vision(Diplopia).
