What are the most common early symptoms of myasthenia gravis?
In more than half of people who develop myasthenia gravis, their first signs and symptoms involve eye problems, such as:
- Drooping of one or both eyelids (ptosis)
- Double vision (diplopia), which may be horizontal or vertical, and improves or resolves when one eye is closed.
What does ocular myasthenia gravis feel like?
The symptoms of ocular myasthenia gravis include double vision (seeing two images instead of one), trouble focusing, and drooping eyelids. On the other hand, generalized myasthenia gravis affects muscles throughout the body.
Can myasthenia gravis affect one eye?
When eye-related symptoms occur, they can affect one or both eyes. Symptoms also vary in severity. People that have generalized myasthenia gravis will also develop muscle weakness in other areas of the body, such as the arms and legs.
How do you test for ocular myasthenia gravis?
A series of tests can be used to diagnose ocular myasthenia gravis, such as serum antibodies, the tensilon test, and electromyography (EMG). These exams are not always able to identify the patients with ocular myasthenia gravis.
What can be mistaken for myasthenia gravis?
Beware: there are other diseases that mimic myasthenia gravis. A number of disorders may mimic MG, including generalized fatigue, amyotrophic lateral sclerosis (ALS), Lambert-Eaton myasthenic syndrome, botulism, penicillamine-induced myasthenia, and congenital myasthenic syndromes.
How long does ocular myasthenia gravis last?
Symptoms usually start to improve 2-4 weeks after treatment is started. Maximum benefit is usually seen after 6-12 months of treatment.

Does myasthenia gravis cause dry eyes?
Ocular irritation may present in some patients with OMG. According to recent studies, dry eye disease may develop in up to 21% of patients; the main reason is lagophthalmos and reduced blinking due to orbicularis muscle weakness [4].
How rare is ocular myasthenia gravis?
Myasthenia gravis (MG) is a rare, autoimmune neuromuscular junction disorder. Contemporary prevalence rates approach 1/5,000.
Do you get headaches with myasthenia gravis?
Among the 184 MG patients who were followed at the MG clinics, tension-type headache was observed in 71 (38.6%) patients and 9 (4.9%) complained of migraine. Twenty-five (13.6%) complained that headache appeared or was exacerbated after the MG onset.
Do you have pain with myasthenia gravis?
Myasthenia gravis itself does not cause pain, but the weakness may lead to non-specific aches and pains. For instance, neck pain may occur because of weakness in the neck muscles. Only the voluntary muscles are affected by myasthenia gravis so the heart and the gastrointestinal tract are spared.
