Optico-ciliary shunt vessels can occur in papilledema. It appears possible that the diameter of these vessels correlates with the pressure in the optic nerve sheath.
A 31-year-old woman with pseudotumor cerebri had atrophic papilledema with optico-ciliary shunt vessels at the disc margin. After optic nerve sheath fenestration these vessels collapsed and ultrasonography revealed a decrease in the nerve sheath diameter. Sixteen days later, the optico-ciliary shunt vessels were filled again. Nine hours after lumbar puncture, the optico-ciliary shunt vessels disappeared for 13 hours, but the nerve sheath diameter did not decrease. After acetazolamide, 1g q d, neither the diameter of the optico-ciliary shunt vessels nor that of the nerve sheath decreased.
The diameter of optico-ciliary shunt vessels may be an indicator of the pressure within the optic nerve sheath.
视睫状分流血管可出现在视乳头水肿中。这些血管的直径似乎与视神经鞘内的压力相关。
一名31岁的假脑瘤女性患者，视盘边缘有萎缩性视乳头水肿及视睫状分流血管。视神经鞘开窗术后，这些血管塌陷，超声检查显示神经鞘直径减小。16天后，视睫状分流血管再次充盈。腰椎穿刺9小时后，视睫状分流血管消失了13小时，但神经鞘直径并未减小。服用乙酰唑胺（每日1克）后，视睫状分流血管直径和神经鞘直径均未减小。
视睫状分流血管的直径可能是视神经鞘内压力的一个指标。
