A common symptom of myasthenia gravis is eyelid ptosis. Often, the edrophonium test is negative, particularly in ocular myasthenia gravis. Myasthenic weakness is often improved by cold. We applied ice packs to the eye in 10 myasthenic patients and 7 disease controls. Eight of 10 patients with myasthenia gravis improved, whereas none of the controls improved. The ice pack test is useful in the diagnosis of myasthenia gravis.
重症肌无力的一个常见症状是眼睑下垂。通常，腾喜龙试验呈阴性，尤其是在眼肌型重症肌无力患者中。重症肌无力导致的肌无力常在遇冷时有所改善。我们对10例重症肌无力患者和7例疾病对照者的眼部使用了冰袋。10例重症肌无力患者中有8例症状改善，而对照组中无人改善。冰袋试验对重症肌无力的诊断有用。
