We evaluated the effect of optic disk edema on spontaneous venous pulsations (SVP) in patients without elevated intracranial pressure (ICP).Prospective, cross-sectional comparison in an institutional setting.
Twenty consecutive patients with unilateral optic disk edema due to anterior ischemic optic neuropathy (AION, n = 11) or optic neuritis (n = 9) were evaluated. The proportion of subjects with SVP in both eyes, the involved eye only, the uninvolved eye only, or neither eye was determined. Comparisons were made using the Exact McNemar Test.
There was a significant difference in the proportion of uninvolved and involved eyes with SVP (60% [12/20] vs 5% [1/20], P <.005). Spontaneous venous pulsations were present in the uninvolved eye of 12 patients and the nonedematous portion of the optic disk in 1 patient with segmental edema from AION.
Optic disk edema may cause SVP cessation without ICP elevation.
我们评估了在颅内压（ICP）未升高的患者中视盘水肿对自发性静脉搏动（SVP）的影响。在机构环境中进行前瞻性横断面比较。
对连续20例因前部缺血性视神经病变（AION，n = 11）或视神经炎（n = 9）导致单侧视盘水肿的患者进行评估。确定双眼均有SVP、仅患眼有SVP、仅未患眼有SVP或双眼均无SVP的受试者比例。使用精确的麦克内马尔检验进行比较。
未患眼和患眼中有SVP的比例存在显著差异（60% [12/20] 对5% [1/20]，P <.005）。12例患者的未患眼存在自发性静脉搏动，1例因AION导致节段性水肿的患者视盘非水肿部分存在自发性静脉搏动。
视盘水肿可能在不升高ICP的情况下导致SVP停止。
