The authors evaluated, by means of colour Doppler imaging, the blood flow in ophthalmic artery and posterior ciliary arteries in subjects with chronic open angle glaucoma. On the basis of the visual field indices (MD, SF, CPSD) the patients' eyes were divided in two groups: group A with better indices and group B with great damage. At the posterior ciliary arteries they found these values: PSV 10.264 +/- 2.363 cm/s (group A) vs. 7.882 +/- 1.251 cm/s (group B) (p < 0.008); RI 0.615 +/- 0.065 (group A) vs. 0.695 +/- 0.064 (group B) (p < 0.009). These data highlight a correlation between the visual field damage and the reduced supply of optic nerve head.
作者通过彩色多普勒成像技术评估了慢性开角型青光眼患者眼动脉和睫状后动脉的血流情况。根据视野指标（平均缺损、短期波动、校正模式标准偏差），将患者的眼睛分为两组：指标较好的A组和损伤严重的B组。在睫状后动脉处，他们得到了以下数值：收缩期峰值速度（PSV），A组为10.264±2.363厘米/秒，B组为7.882±1.251厘米/秒（p<0.008）；阻力指数（RI），A组为0.615±0.065，B组为0.695±0.064（p<0.009）。这些数据突出了视野损伤与视神经乳头供血减少之间的相关性。
