True isolated sixth nerve palsy as the initial presentation of multiple sclerosis (MS) is rare. MS is a chronic inflammatory, immune-mediated disease of the central nervous system. This is the most common cause of neurological disability in young adults. Common symptoms include acute episodes of muscle weakness, altered sensation, balance and gait disturbances, visual loss and bladder dysfunction.Diagnosis of MS is supported with the incidence of symptomatic clinical episodes with subsequent cross-sectional imaging to confirm radiological lesions that are disseminated in space and time.In the following report, we discuss the case of a woman in her 30s who presented to ophthalmology with a sixth nerve palsy in the absence of ocular or systemic disease. This is the first presentation of MS, a rare clinical event.
真正孤立性第六脑神经麻痹作为多发性硬化症（MS）的初始表现较为罕见。MS 是一种中枢神经系统的慢性炎症性、免疫介导性疾病。这是年轻人中最常见的神经功能障碍原因。常见症状包括急性肌肉无力发作、感觉改变、平衡和步态障碍、视力丧失和膀胱功能障碍。MS 的诊断依据是有症状的临床发作的发生率，随后进行横断面成像以确认在空间和时间上弥散的放射学病变。在下面的报告中，我们讨论了一位 30 多岁的女性患者，她因第六脑神经麻痹就诊于眼科，而眼部或全身均无疾病。这是 MS 的首次表现，是一种罕见的临床事件。
