Some ocular diseases lead to temporary changes in the ocular blood circulation. This study was undertaken to evaluate changes in the blood-flow velocity of the ophthalmic artery in patients with endophthalmitis. With pulsed Doppler sonography the blood velocity of the ophthalmic artery was measured in 50 normal subjects and in ten patients with bacterial endophthalmitis. In normal subjects blood velocity decreased with increasing age, and the average systolic/diastolic blood velocity in cm/sec were 38.8 +/- 6.3/11.6 +/- 4.7 in the 18-50-year-old age group and 28.3 +/- 4.6/6.7 +/- 3.3 in the 51-88-year-old age group. Endophthalmitis produced increased systolic/diastolic blood velocity in the ophthalmic artery in the affected eyes in cm/sec (99.7 +/- 15.5/26.6 +/- 10.5 in the 16-50-year-old age group; 60.4 +/- 8.8/16.6 +/- 4.8 in the 51-83-year-old age group). Some patients showed similar changes in the unaffected fellow eyes. The noted elevation of the blood velocity in unaffected eyes may be due to the bilaterally projected parasympathetic fibers of the oculomotor nerve.
一些眼部疾病会导致眼部血液循环的暂时变化。本研究旨在评估眼内炎患者眼动脉血流速度的变化。采用脉冲多普勒超声检查，测量了50名正常受试者和10名细菌性眼内炎患者的眼动脉血流速度。在正常受试者中，血流速度随年龄增长而降低，18 - 50岁年龄组的平均收缩/舒张血流速度（厘米/秒）为38.8±6.3/11.6±4.7，51 - 88岁年龄组为28.3±4.6/6.7±3.3。眼内炎导致患眼眼动脉收缩/舒张血流速度增加（厘米/秒）（16 - 50岁年龄组为99.7±15.5/26.6±10.5；51 - 83岁年龄组为60.4±8.8/16.6±4.8）。一些患者的未受影响的对侧眼也出现了类似变化。未受影响眼血流速度的明显升高可能是由于动眼神经的双侧投射副交感纤维所致。
