The clinical features and therapeutic aspects of 94 patients with myasthenia gravis seen in the Neurology Institute, General Hospital Colombo, over an eight year period are analysed. The manifestations were similar to that described in the West, but there was a preponderance of male patients, and the ocular myasthenics showed a better response to anticholinesterase medication than described in the world literature. The response to treatment with anticholinesterases, steroids, plasma exchange and thymectomy are assessed.
