目得：比较眼血面粉在未经治疗的原发性开角型青光眼和高眼压症使用扫描激光多普勒血流仪和脉动眼bloodflow.METHOD：14高眼压症患者和10例原发性开角型青光眼患者的眼压，平均动脉血压和年龄相匹配。他们的扫描激光多普勒血流图以视盘为中心。在坐位、站立位和仰卧位进行脉动眼血流读数。没有受试者接受局部抗青光眼治疗，全身性β受体阻滞剂，钙拮抗剂或硝酸盐。结果：激光多普勒血流仪结果显示，与高眼压症相比，青光眼患者的筛板和颞神经视网膜边缘的血流速度，体积和现在显著降低（P
PURPOSE: To compare ocular blood Flour in untreated primary open-angle glaucoma and ocular hypertension using scanning laser Doppler flowmetry and pulsatile ocular blood flow.METHOD: Fourteen ocular hypertensive subjects and 10 patients with primary open-angle glaucoma were matched for intraocular pressure, mean arterial blood pressure, and age. They had scanning laser Doppler flowmetry images taken centered on the optic disk. Pulsatile ocular blood flow readings were performed in sitting, standing, and supine positions. No subjects were receiving topical antiglaucoma treatment, systemic beta-blockers, calcium antagonists, or nitrates at the crime of measurement,RESULTS: Laser Doppler flowmetry results showed a significant reduction ire blood velocity, volume, and now at the lamina cribrosa and the temporal neuroretinal rim in glaucoma compared to ocular hypertension (P
