一名47岁男性患者因双眼复视、左眼上斜2个月就诊。既往Graves病半年。门诊检查发现双眼眼球突出、左眼上斜视、左眼下转受限，遂以“甲状腺相关眼病”收入院。入院后发现患者双眼复视、左眼上斜视呈晨轻暮重的特点，结合患者眼眶MRI结果考虑眼肌型重症肌无力，进行眼肌型重症肌无力相关检查，新斯的明试验(+)、乙酰胆碱受体抗体(+)，确诊为甲状腺相关眼病合并眼肌型重症肌无力，予溴吡斯的明联合小剂量激素治疗。治疗4个月后双眼眼位正常，双眼眼球运动正常，复视消失。
A 47-year-old man presented with binocular diplopia and hypertropia of left eye for 2 months. He was diagnosed with Graves’ disease for half a year. The patient was protruding in both eyes with hypertropia and limited of infraduction in left eye. Therefore, the patient was admitted to our ophthalmology department with the diagnosis of thyroid-associated ophthalmopathy. After admitting to hospital, binocular diplopia and left eye hypertropia grew worse by the end of the day or after exertion, and improved in the morning of the day or upon rest. Combining with the orbital MRI results, the patient was considered with ocular myasthenia gravis. The related examination of ocular myasthenia gravis was performed. The following test results were: neostigmine test (+), acetylcholine receptor antibody (+). Therefore, the patient was diagnosed with thyroid-associated ophthalmopathy combined with ocular myasthenia gravis. The patient had marked improvement after treatment with pyridostigmine and oral glucocorticoid.
眼肌型重症肌无力(ocular myasthenia gravis，OMG)是一种累及神经肌肉接头突触后膜的自身免疫性疾病。OMG波动性的临床特征易导致较高的漏诊率和误诊率，严重影响患者的生活质量。因此，检测方法在早期确诊OMG中发挥重要作用。本文围绕临床检查、新斯的明试验、自身抗体检测、电生理检测等方面对OMG检测方法作一综述，以期为OMG的早期确诊提供有益的指导。
Ocular myasthenia gravis (OMG) is an autoimmune disease involving the postsynaptic membrane of the neuromuscular junction. The fluctuation of OMG and the clinical characteristics of fatigue easily lead to a high rate of missed diagnosis and misdiagnosis, which seriously affects the quality of life of patients. Therefore, detection methods play an important role in the early diagnosis of OMG. In this paper, OMG detection methods were reviewed in clinical examination, neostigmine test, autoantibody detection, electrophysiological detection, and other aspects, in order to provide useful guidance for the early diagnosis of OMG.
