Corneal touch thresholds were measured in 11 people suffering from myasthenia gravis (MG) and in a control group of 20 subjects. The mean threshold in MG was 75.6 mg (SD 52) and in the control group 18.9 mg (SD 7.3); thresholds were thus significantly (p less than 0.01) raised in MG. Although it is not possible to say whether the sensory deficit is due to MG or to the treatment, the results implicate acetylcholine in sensory transduction in the cornea.
对11名重症肌无力（MG）患者和20名对照组受试者测量了角膜触觉阈值。MG组的平均阈值为75.6毫克（标准差52），对照组为18.9毫克（标准差7.3）；因此MG组的阈值显著升高（p小于0.01）。虽然无法确定感觉缺陷是由MG还是治疗引起的，但结果表明乙酰胆碱参与了角膜的感觉传导。
