Ocular pneumoplethysmography (OPG), a semiautomated form of suction ophthalmodynamometry, was used to evaluate and follow 15 patients who underwent carotid endarterectomy and two patients in whom gradual carotid artery occlusion was performed for inoperable intracranial aneurysm. Postoperative corrected ophthalmic arterial pressures (COAP's) on the operated side in the carotid endarterectomy patients averaged 12.5 mm Hg higher than before surgery, the standard deviation being 4.9 mm Hg for clinically stable patients. There was no significant change in COAP on the contralateral side. Several problems were encountered in closing down carotid clamps, the most potentially serious being a precipitous fall in COAP with the final adjustment. The current uses of OPG and similar techniques are reviewed, and potential neurosurgical applications are discussed.
眼体积描记法（OPG），一种半自动的吸引式眼压测量法，被用于评估和随访15例行颈动脉内膜切除术的患者以及2例因颅内动脉瘤无法手术而进行颈动脉逐渐闭塞术的患者。颈动脉内膜切除术患者手术侧术后校正眼动脉压（COAP）平均比术前高12.5 mmHg，临床稳定患者的标准差为4.9 mmHg。对侧的COAP没有显著变化。在关闭颈动脉夹时遇到了几个问题，最具潜在严重性的是在最后调整时COAP急剧下降。本文回顾了OPG及类似技术的当前应用，并讨论了其在神经外科的潜在应用。
