Abstract
This report illustrates the potential of the optic subarachnoid space to dilate selectively with various disease processes involving the orbit, optic canal, sella, and parasellar regions. According to the concept of optic hydrops, isolated papilledema, in the absence of increased intracranial pressure, may be caused by focal disease of these regions.
摘要
本报告阐述了视交叉蛛网膜下腔在涉及眼眶、视神经管、蝶鞍和鞍旁区域的各种疾病过程中选择性扩张的可能性。根据视乳头水肿的概念，在颅内压不升高的情况下，孤立性视乳头水肿可能由这些区域的局灶性疾病引起。
