To investigate retrobulbar blood flow changes in the short posterior ciliary arteries (SPCAs) in patients with pseudoexfoliation glaucoma (PEG) and primary open-angle glaucoma (POAG).
In this prospective study, there were 22 eyes in the PEG group, 28 eyes in the POAG group, and 28 eyes with senile cataract in the control group. Peak systolic velocity (PSV), end-diastolic velocity (EDV), mean velocity (Vm), and resistivity index (RI) parameters of the temporal and nasal SPCAs were compared between the study groups.
Mean temporal PSV, EDV, and Vm value were significantly lower in both the POAG group and the PEG group ( = 0.049, = 0.004, = 0.020), respectively. Temporal SPCA RI values were not significantly different between the groups ( = 0.115).
There are retrobulbar blood flow changes in glaucomatous compared to nonglaucomatous eyes. However, SPCAs blood flow characteristics are similar between PEG and POAG subtypes.
研究假性剥脱性青光眼（PEG）和原发性开角型青光眼（POAG）患者睫状后短动脉（SPCA）的球后血流变化。
在这项前瞻性研究中，PEG组有22只眼，POAG组有28只眼，对照组有28只患有老年性白内障的眼睛。比较各研究组颞侧和鼻侧SPCA的收缩期峰值速度（PSV）、舒张末期速度（EDV）、平均速度（Vm）和阻力指数（RI）参数。
POAG组和PEG组的平均颞侧PSV、EDV和Vm值均显著较低（分别为=0.049，=0.004，=0.020）。各研究组间颞侧SPCA的RI值无显著差异（=0.115）。
与非青光眼眼相比，青光眼患者存在球后血流变化。然而，PEG和POAG亚型之间SPCA的血流特征相似。
