To look for a correlation between or the effect of anisometropia amblyopia on retrobulbar blood flow parameters. Peak systolic velocity (PSV) and end-diastolic velocity (EDV) of the ophthalmic artery (OA), central retinal artery (CRA), and temporal posterior ciliary artery (tPCA) were measured with color Doppler imaging, and systolic/diastolic ratio, resistivity index (RI), and pulsatility index (PI) were computed in 42 patients with anisometropic amblyopia. The mean PSV of OA, CRA, and tPCA in amblyopic and fellow eyes were 62.69 ± 24.04, 62.64 ± 20.18; 9.28 ± 3.71, 10.27 ± 4.18; 10.81 ± 4.59, 11.28 ± 4.91, respectively. The mean EDV of OA, CRA, and tPCA in amblyopic and fellow eyes were 15.87 ± 11.31, 14.52 ± 6.54; 2.48 ± 1.17, 2.62 ± 2.06; 3.04 ± 2.34, 3.14 ± 2.18, respectively. The mean RI of OA, CRA, and tPCA in amblyopic and fellow eyes were 0.76 ± 0.08, 0.76 ± 0.08; 0.72 ± 0.08, 0.74 ± 0.95; 0.72 ± 0.09, 0.72 ± 0.08, respectively. The mean PI of OA, CRA, and tPCA in amblyopic and fellow eyes were 1.77 ± 0.42, 1.81 ± 0.46; 01.58 ± 0.42, 1.59 ± 0.43; 1.54 ± 0.43, 1.58 ± 0.49, respectively. There was no statistically significant difference in any of the measured parameters between the amblyopic and fellow eyes. Anisometropic amblyopia did not cause any change in retrobulbar blood flow in amblyopic eyes.
探究屈光参差性弱视与球后血流参数之间的相关性或其影响。采用彩色多普勒成像测量42例屈光参差性弱视患者眼动脉（OA）、视网膜中央动脉（CRA）和颞侧睫状后动脉（tPCA）的收缩期峰值流速（PSV）和舒张末期流速（EDV），并计算其收缩/舒张比、阻力指数（RI）和搏动指数（PI）。弱视眼和对侧眼的OA、CRA和tPCA的平均PSV分别为62.69±24.04、62.64±20.18；9.28±3.71、10.27±4.18；10.81±4.59、11.28±4.91。弱视眼和对侧眼的OA、CRA和tPCA的平均EDV分别为15.87±11.31、14.52±6.54；2.48±1.17、2.62±2.06；3.04±2.34、3.14±2.18。弱视眼和对侧眼的OA、CRA和tPCA的平均RI分别为0.76±0.08、0.76±0.08；0.72±0.08、0.74±0.95；0.72±0.09、0.72±0.08。弱视眼和对侧眼的OA、CRA和tPCA的平均PI分别为1.77±0.42、1.81±0.46；01.58±0.42、1.59±0.43；1.54±0.43、1.58±0.49。弱视眼和对侧眼之间的任何测量参数均无统计学显著差异。屈光参差性弱视不会导致弱视眼球后血流发生任何变化。
