Upper eyelid retraction disclosed after edrophonium chloride administration in a patient with Graves' orbitopathy and myasthenia gravis Full Text
Clinical Ophthalmology, 06/01/2012
Kang H et al. – The authors herein report a patient with Graves' orbitopathy and myasthenia gravis (GO–MG) with normal left eyelid height, but in whom upper eyelid retraction was shown after edrophonium chloride administration. Upper eyelid retraction in GO–MG is occasionally masked by a myasthenia effect. The upper eyelid height must be carefully monitored in patients with Graves' orbitopathy to detect the presence of concomitant myasthenia gravis.
