ocular myasthenia

A form of myasthenia gravis characterized by fluctuating weakness of the extraocular muscles, resulting in ptosis (drooping eyelid) and diplopia (double vision). Symptoms typically worsen with prolonged use of the eyes and improve with rest. It is caused by an autoimmune attack on acetylcholine receptors at the neuromuscular junction. Diagnosis involves clinical tests and antibody testing. Treatment includes medications to improve neuromuscular transmission and suppress the immune system.
