Oculopharyngeal Muscular Dystrophy (OPMD) is a rare, inherited form of muscular dystrophy that affects the eyes, throat, and upper arms. It is characterized by progressive weakness and wasting of the muscles of the eyes, throat, and upper arms. Symptoms typically begin in adulthood and include drooping eyelids, difficulty swallowing, and weakness in the shoulder and arm muscles. OPMD is caused by a mutation in the PABPN1 gene. Treatment is focused on managing symptoms and may include physical therapy, speech therapy, and medications.
