Diplopia (double vision) caused by a problem with the muscles that control the movement of the eye or the nerves that stimulate those muscles.
The onset of double vision in adulthood should be brought to the attention of your ophthalmologist immediately to exclude the possibility of a tumor, aneurysm, or neurological problem. Two of the primary neurological conditions that could cause diplopia are microvascular cranial nerve palsy and myasthenia gravis .
Microvascular cranial nerve palsy is one of the most common causes of double vision in older people. It occurs more often in patients with diabetes and high blood pressure, when blood flow is blocked to one or more of the six eye muscles that control eye movement. Although there is no known treatment for microvascular cranial nerve palsy, the double vision may alleviated by placing a prism on your spectacles or wearing an eye patch.
Myasthenia gravis is a disorder characterized by muscle weakness, caused by a communication breakdown between the nerves and the muscles due to an autoimmune condition. It is most common in the muscles of the face, eyes, arms, and legs, and in those involved in chewing, swallowing, and talking. Double vision is one of the common indicators of myasthenia gravis. Though there is no known cure for myasthenia gravis, there are a number of treatment options to manage the condition, including medications, physical therapy and surgery. Early detection and treatment of myasthenia gravis is crucial to managing the condition and preventing serious problems with breathing or swallowing, which can require emergency care.
