Twenty harpy eagles () without systemic or ocular diseases were examined to measure blood velocity parameters of the artery using Doppler ultrasonography. Pectinate artery resistive index (RI) and pulsatility index (PI) were investigated using ocular Doppler ultrasonography. The mean RI and PI values across all eyes were 0.44±0.10 and 0.62±0.20 respectively. Low RI and PI values found in the harpy eagle´s artery compared with the American pekin ducks one and other tissue suggest indeed a high metabolic activity in and corroborates the hypothesis of a nutritional function and/or intraocular pressure regulation.
对20只无全身或眼部疾病的食猿雕进行检查,使用多普勒超声测量动脉的血流速度参数。使用眼部多普勒超声研究栉膜动脉阻力指数(RI)和搏动指数(PI)。所有眼睛的平均RI和PI值分别为0.44±0.10和0.62±0.20。与美国北京鸭及其他组织相比,食猿雕动脉中发现的低RI和PI值确实表明其具有高代谢活性,这证实了营养功能和/或眼内压调节的假设。
