A 27-year-old woman with a known suprasellar dermoid cyst and stable idiopathic intracranial hypertension (IIH) presented with new monocular vision change and new-onset headaches. Formal visual field testing accurately identified progressive chiasmal compression due to her suprasellar dermoid cyst before radiographic change was appreciable on magnetic resonance imaging. Accurate interpretation of her visual field findings avoided the common pitfall of attributing new visual symptoms to her IIH diagnosis. This case highlights the value of recognizing visual field changes that localize to the chiasm even in patients with history of other ophthalmologic conditions.
一位 27 岁女性，已知患有鞍上皮样囊肿和稳定型特发性颅内高压（IIH），出现新的单眼视力改变和新发头痛。正式的视野测试准确地识别出由于她的鞍上皮样囊肿导致的视交叉进行性压迫，而在磁共振成像上可观察到的放射影像学改变之前。对她的视野检查结果的准确解释避免了将新的视觉症状归因于她的 IIH 诊断的常见陷阱。本病例强调了即使在有其他眼科疾病病史的患者中，识别定位于视交叉的视野变化的价值。
