See-saw nystagmus (SSN) is a rare form of nystagmus characterised by alternating elevation with incyclotorsion of one eye and concomitant depression with excyclotorsion of the other eye, often due to abnormalities involving the midbrain and parasellar region. Herein, we highlight a rare case of pendular SSN, which demonstrated complete resolution following resection of a pituitary macroadenoma. A patient in their 40s was identified to have SSN and was diagnosed with a pituitary macroadenoma. They underwent an endoscopic endonasal transsellar approach for resection of the pituitary adenoma. Their nystagmus resolved immediately after surgery. From a review of the literature, resolution and/or significant improvement in SSN occurred in 74% of cases following treatment, with 100%, 86% and 50% following treatment for medication-induced, neurological infarcts, and mass-effect aetiologies of SSN, respectively. SSN is a rare entity with a wide array of aetiologies. Identification of the causative aetiology and appropriate treatment can lead to significant improvement or resolution of the nystagmus in most cases.
跷跷板样眼球震颤（SSN）是一种罕见的眼球震颤形式，其特征为一只眼睛交替性上抬并伴有眼球内旋，同时另一只眼睛交替性下转并伴有眼球外旋，通常是由于中脑和鞍旁区域的异常所致。在此，我们重点介绍一例罕见的钟摆型SSN病例，该病例在切除垂体大腺瘤后眼球震颤完全消失。一名40多岁的患者被确诊患有SSN，并被诊断为垂体大腺瘤。他们接受了经鼻内镜经蝶窦入路垂体腺瘤切除术。术后其眼球震颤立即消失。通过文献回顾发现，74%的病例在接受治疗后SSN得到缓解和/或显著改善，其中因药物诱导、神经梗死和SSN的占位效应病因接受治疗后，缓解率分别为100%、86%和50%。SSN是一种病因多样的罕见病症。在大多数情况下，识别病因并进行适当治疗可使眼球震颤得到显著改善或消失。
