Abstract：
BACKGROUND: To report a case of tuberculum meningioma with recovery of glaucoma-like visual field defects after chiasmal decompression.
METHODS: A 39-year-old woman presenting with headache was found to have bilateral arcuate retinal nerve fiber layer (RNFL) thinning on optical coherence tomography (OCT) with a corresponding arcuate scotomas consistent with glaucomatous change. However a suprasellar tumor compressing the anterior chiasm from below was found on magnetic resonance imaging of the brain. After resection of the mass, which was diagnosed as meningothelial meningioma by the pathological examination, the glaucoma-like visual field defects resolved despite the RNFL thinning on the OCT showing no improvement.
CONCLUSIONS: Chiasmal compression may mimic glaucoma and produce arcuate scotoma rather than temporal visual field loss. There is a possibility that the development of chiasmal compression somehow converted preperimetric glaucoma into a more advanced form accompanied by visual field defects and that the glaucoma reverted to the preperimetric state after chiasmal decompression.

摘要：
背景：报告1例结核性脑膜瘤经泪道减压术后青光眼样视野缺损恢复的病例。
方法：一名出现头痛的39岁女性患者在光学相干断层扫描（OCT）上发现双侧弓状视网膜神经纤维层（RNFL）变薄，相应的弓状暗点与青光眼改变一致。然而，在大脑的磁共振成像中发现了从下方压迫前交叉的鞍上肿瘤。切除肿块后,病理检查诊断为脑膜上皮脑膜瘤，尽管OCT上的RNFL变薄显示无改善,但青光眼样视野缺损得以解决.
结论：Chiasmal压迫可能模拟青光眼并产生弓形暗点，而不是颞部视野丧失。有一种可能性是，交叉压迫的发展以某种方式将眼前青光眼转化为伴有视野缺损的更晚期形式，并且在交叉减压后青光眼恢复到眼前状态。
