Ocular dysfunction accounts for nearly 70% of the initial manifestations of myasthenia gravis. Since the prevalence rate of myasthenia gravis is two to 10 cases per 100,000 population, it is important for clinicians to be cognizant of this disorder and its varied ocular presentations. The clinical manifestations, diagnosis, treatment, and prognosis of ocular myasthenia gravis are reviewed.

UI	MeSH Term	Description	Entries

D009157	Myasthenia Gravis	A disorder of neuromuscular transmission characterized by fatigable weakness of cranial and skeletal muscles with elevated titers of ACETYLCHOLINE RECEPTORS or muscle-specific receptor tyrosine kinase (MuSK) autoantibodies. Clinical manifestations may include ocular muscle weakness (fluctuating, asymmetric, external ophthalmoplegia; diplopia; ptosis; and weakness of eye closure) and extraocular fatigable weakness of facial, bulbar, respiratory, and proximal limb muscles. The disease may remain limited to the ocular muscles (ocular myasthenia). THYMOMA is commonly associated with this condition.
