To describe a visual complication of optic nerve sheath fenestration.
Case review of two patients who underwent seemingly uncomplicated optic nerve sheath fenestration.
Both patients had a surgical complication that resulted in significant depression of their temporal visual field and development of a wedge-shaped region of subretinal pigmentation in the nasal fundus.
Both patients had choroidal infarctions as a complication of optic nerve sheath fenestration. Choroidal infarction should be considered in cases of unexpected loss of visual field after this type of surgery, although the funduscopic signs that assist in making the diagnosis may not be evident for several weeks after surgery.
描述视神经鞘开窗术的一种视觉并发症。
对两名接受看似简单的视神经鞘开窗术的患者进行病例回顾。
两名患者均出现手术并发症，导致颞侧视野显著缺损，并在眼底鼻侧出现楔形视网膜下色素沉着区域。
两名患者均发生脉络膜梗死，作为视神经鞘开窗术的并发症。在这类手术后出现意外视野丧失的病例中，应考虑脉络膜梗死，尽管有助于诊断的眼底体征在手术后数周可能不明显。
