Doctors treat double vision, or diplopia, based on its underlying cause, notes WebMD. They may recommend surgery for weak or pinched eye muscles or prescribe medications to treat double vision due to myasthenia gravis. Doctors treat diabetics who suffer from double vision with medications, and, in some cases, with insulin. People who cannot find effective treatments may wear eye patches or glasses to minimize their double vision.
People with weak eye muscles and double vision may suffer from strabismus, which causes the eye muscles to fail to work together, according to Healthline. Doctors perform eye muscle repair surgery by making an incision in the membrane covering the eye and either shortening or stretching the eye muscles. The effects of eye muscle surgery on double vision are usually immediate, although the resulting muscle weakness causes vision problems and takes time to heal.
Myasthenia gravis blocks neurotransmitters in the eye muscles, causing weakness, as Mayo Clinic explains. Doctors may treat double vision caused by myasthenia gravis with medications, such as cholinesterase inhibitors, corticosteroids and immunosuppressants, or through plasmapheresis or intravenous immunoglobulin therapies. People suffering from double vision that is new or does not have a known cause should seek medical attention immediately.
