title: Ocular Myasthenia Gravis.
abstract: Treatment decisions for ocular myasthenia gravis (OMG) should be based on symptomatology. Local, nonpharmacologic treatment of ptosis or diplopia is successful in relatively few patients, and the majority of patients require drug therapy for satisfactory resolution of their symptoms. Response to anticholinesterase agents is variable, but should always be used as the first-line agent or adjunctive therapy in the treatment of OMG. It is unknown whether early treatment of OMG with corticosteroids or other immunosuppressive agents prevents or delays the development of generalized myasthenia, although some observations support this speculation. Corticosteroids are usually necessary for adequate improvement of ophthalmoplegia or ptosis. Surgical correction of ptosis or ocular motility deficits is not recommended for most patients with OMG, because of the fluctuating nature of the deficits and the high rate of recurrent deficits following surgery. All patients with OMG should be screened for the presence of thymus tumors, and thymectomy is recommended for all patients with a thymoma. Some patients with OMG who do not harbor a thymus tumor may also benefit from thymectomy.
