AN EVALUATION OF SIGNS IN OCULAR MYASTHENIA GRAVIS AND CORRELATION WITH ACETYLCHOLINE RECEPTOR ANTIBODIES

Fifteen patients with ocular myasthenia gravis were examined in detail for 21 different signs, and tested for acetylcholine receptor antibodies. The major signs of ocular myasthenia gravis included ptosis, disorders of ocular rotations, weakness of eyelid closure, "pseudosupranuclear" signs and the lid twitch sign. Acetylcholine receptor antibodies were found in eight of the 15 patients. One hundred and four normal, non-myasthenic patients were also examined for the lid twitch response, and the relationship between the lid twitch of ocular myasthenia gravis and that found in normal subjects is discussed.
