Using eyelid crutches (clever devices attached to glasses to hold the eyelids open) for ptosis.

Therefore, it is important to alternate the patch from one eye to the other to avoid permanent vision loss. If the same eye is consistently patched, vision in that eye might decrease. This permits people with double vision to see one image. This can be used for ptosis and may be preferable to drug therapy that alters the immune system: using agents such as glucocorticoids (prednisone or similar agents), azathioprine (Imuran®), cyclosporine or mycophenolate mofetil (CellCept®).

Using eyelid tape (a special type of tape used to hold the eyelids open without injuring the eyelids).

Wearing dark glasses in bright light, which some people find helpful.

People who have primarily cosmetic problems due to ptosis or diplopia may consider nonpharmacological treatment, such as: It is important to talk with your physician about the best treatment regimen for you-balancing the severity of the symptoms and impact on quality of life with the risks and benefits of treatment.

The differences in the response of eye muscles to immune attack may explain why eye muscles are also targeted in other autoimmune conditions, such as autoimmune thyroid disease. Perhaps the most important difference between eye and eyelid muscles compared with other muscles of the body is that eye muscles respond differently to immune attack. Eye muscles contract much more rapidly than other muscles and may be more likely to fatigue. For example, these parts of the body have fewer acetylcholine (AChR) receptors, which is where the defect occurs in autoimmune MG. Another hypothesis is that the eye and eyelid muscles are structurally different from muscles in the trunk and limbs. One hypothesis is that people with MG may simply notice eye weakness more often than mild weakness in other muscle groups in the body. However, this is not completely understood. There may be several reasons why eye muscles are more frequently involved. Why are the eye muscles frequently involved in myasthenia gravis? People with ocular MG are slightly more likely to have seronegative MG (no measurable autoantibodies like AChR and MuSK) compared with people with generalized MG. People that have had only ocular MG symptoms for five years or more will most likely not develop generalized MG. About half of all people with ocular issues related to MG in the first year will develop generalized MG. If weakness of other muscles develops over time, the MG changes from ocular MG to generalized MG. About 15% of people with MG will have only ocular problems (ocular MG). Although most people have eye problems at the onset of MG, they may have other muscle weakness or develop other muscle weakness in the first two years after MG symptoms begin. Problems with double vision and drooping eyelids are often the first symptoms of MG. The medical term for drooping eyelids is ptosis (pronounced “toe-sis”). If the eyelid covers the pupil of the eye, then the vision of that eye will be obstructed. Drooping eyelids – The eyes do not appear to be opened fully.If you have diplopia, you may experience blurred vision rather than double vision.

The medical term for double vision is diplopia. This results from weakness of the muscles that move the eyes together in alignment. Double vision – Seeing two images rather than one.Descriptions of the symptoms that people with ocular MG may have include: People with ocular MG do not have difficulty swallowing, speaking or breathing, nor do they have weakness of the arms or legs. If you have ocular MG, you may find that eye problems temporarily improve after several minutes of rest. Eye problems often worsen at the end of the day or after a prolonged period of use. Eye weakness often changes from day to day and over the course of a day. One or both eyelids may droop to cover all or part of the pupil of the eye, blocking vision. Their eyes do not move together in balanced alignment, causing them to see “double” images. People with ocular MG have trouble with sight due to double vision and/or drooping eyelids. What are the common symptoms of ocular myasthenia gravis? Ocular myasthenia gravis is a form of myasthenia gravis (MG) in which the muscles that move the eyes and control the eyelids are easily fatigued and weakened.
