Oculogyric crisis (OGC) is a dystonic movement disorder of varying durations that manifests as bilateral paroxysmal upward eye deviation accompanied by involuntary blinking, tongue protrusion, and autonomic symptoms. Separately, septo-optic dysplasia (SOD) is a congenital disorder involving hypoplasia of the optic nerve as well as hypothalamic and pituitary abnormalities. In the presented case, we report a case of OGC in the setting of SOD with proposed pathogenesis.
A 27-year-old female presented with a history of SOD (optic nerve hypoplasia and hypopituitarism) with acute, recurrent, painless, bilateral, intermittent, simultaneous tonic conjugate upward eye deviation (i.e., OGC) and dystonic body posturing. She experienced her first episode upon meeting her biological sister for the first time at a loud, crowded public restaurant with continued episodes of OGC increasing in frequency and duration over the subsequent months. She later responded well to treatment with carbidopa/levodopa.
Based on our current understanding of OGC, we hypothesize that acute stressful life events in the setting of prior hypothalamic-pituitary axis dysfunction secondary to SOD could lower the threshold for developing OGC. Although most cases of OGC are idiopathic, various etiologies including medications, stress, and hormonal imbalance have been postulated as possible pathogenic mechanisms. We describe a case of SOD with OGC, and based upon our review of the English language ophthalmic literature, we believe that our case is novel.
动眼危象(OGC)是一种持续时间各异的肌张力障碍性运动障碍,表现为双侧阵发性向上眼球偏斜,并伴有不自主眨眼、伸舌及自主神经症状。另外,视隔发育不良(SOD)是一种先天性疾病,涉及视神经发育不全以及下丘脑和垂体异常。在本病例报告中,我们报道了一例伴有推测发病机制的SOD合并OGC病例。
一名27岁女性,有SOD病史(视神经发育不全和垂体功能减退),出现急性、复发性、无痛性、双侧、间歇性、同时性强直性共轭向上眼球偏斜(即OGC)以及肌张力障碍性身体姿势。她在一家嘈杂拥挤的公共餐厅首次与亲姐姐见面时首次发作,随后数月OGC发作频率和持续时间不断增加。她后来对卡比多巴/左旋多巴治疗反应良好。
基于我们目前对OGC的理解,我们推测,在继发于SOD的下丘脑 - 垂体轴功能障碍背景下,急性应激性生活事件可能会降低发生OGC的阈值。尽管大多数OGC病例为特发性,但包括药物、压力和激素失衡在内的各种病因已被假定为可能的致病机制。我们描述了一例SOD合并OGC的病例,并且基于我们对英文眼科文献的回顾,我们认为我们的病例具有新颖性。
