PURPOSE OF REVIEW: Ocular myasthenia gravis (OMG) is a complex condition with heterogenous phenotypes and ill-defined diagnostic criteria. Understanding concomitant risk factors and autoimmune serology can help inform prognosis for generalization and guide treatment.
RECENT FINDINGS: Although antibodies to acetylcholine receptors or muscle-specific kinase likely increase risk of generalization, they are less frequent in OMG. Patients without either antibody tend to have a milder disease process and often have variable antibodies to other end-plate proteins such as LRP4, agrin, or cortactin. The treatment of OMG begins with pyridostigmine and is supplemented by oral prednisone if treatment-resistant or high risk for generalization. Variable oral prednisone regimens have been used with success and further immunosuppression may be best achieved with mycophenolate mofetil and azathioprine. Checkpoint inhibitor-induced myasthenia gravis is increasingly recognized and likely has high rates of mortality associated with myocarditis.
SUMMARY: Our understanding of OMG and its variable phenotypes continues to evolve. Autoantibody testing increasingly provides valuable diagnostic and prognostic information. Despite these improvements, a lack of quality treatment trials creates significant challenges for evidence-based management guidelines.
