Fluorescein angiography without sedative or anesthetic agents was evaluated in 20 normal goats and 20 normal sheep. All of the angiographic phases were observed using 20 mg/kg fluorescein IV in both species. Fundus fluorescein angiography results revealed wide stars of Winslow in the tapetal fundus, central or marginal flow during the first part of the arterial phase, delayed filling of the focal areas in the choroid near the optic disc that often coincided with others in the disc, and lack of evidence of the 'striate area' in the tapetal fundi. In goats, the angiographic times were 6.54+/-1.25 s for the arterial phase (TA), 7.80+/-1.37 s for the arterio-venous phase (TAV), and 14.13+/-2.01 s for the venous phase (TV). I1: 1.30+/-0.30 s (time elapsing between TA and TAV), and I2: 6.20+/-1.60 s (time elapsing between TAV and TV). In sheep, times were 9.54+/-2.18 s TA, 11.73+/-2.10 s TAV, and 20.86+/-2.74 s TV. I1: 2.04+/-0.75 s and I2: 8.98+/-2.47 s, respectively. Due to the large size of the fundic vessels in sheep and goats, fluorescein angiography of the retinal vasculature can facilitate the study of the different vascular diseases in these species.
在20只正常山羊和20只正常绵羊中评估了未使用镇静剂或麻醉剂的荧光素血管造影。在这两个物种中，均使用20mg/kg荧光素静脉注射观察所有血管造影阶段。眼底荧光素血管造影结果显示，在绒毡层眼底有广泛的温斯洛星，动脉期第一部分出现中央或边缘血流，视盘附近脉络膜局灶性区域充盈延迟，且常与视盘中的其他区域一致，并且在绒毡层眼底缺乏“纹状区”的证据。在山羊中，动脉期血管造影时间（TA）为6.54±1.25秒，动静脉期（TAV）为7.80±1.37秒，静脉期（TV）为14.13±2.01秒。I1：1.30±0.30秒（TA与TAV之间的时间间隔），I2：6.20±1.60秒（TAV与TV之间的时间间隔）。在绵羊中，TA时间为9.54±2.18秒，TAV为11.73±2.10秒，TV为20.86±2.74秒。I1分别为2.04±0.75秒，I2为8.98±2.47秒。由于绵羊和山羊眼底血管较大，视网膜血管荧光素血管造影有助于研究这些物种中的不同血管疾病。
