title: Penicillamine-induced ocular myasthenia gravis.
abstract: Two patients with rheumatoid arthritis (two women, 58 and 62 years old) developed reversible penicillamine-induced ocular myasthenia gravis. Both had the HLA-DR1 antigen, unlike most patients with idiopathic myasthenia gravis who show HLA-DR3, suggesting that penicillamine-induced myasthenia gravis and its idiopathic counterpart occur in patients with different genetic backgrounds. In both cases, cessation of drug treatment led to resolution of the symptoms.
