This study was designed to quantitatively determined blood flow to the extraocular muscles (EOM) of animals showing a wide range of ocular motility Blood-flow values (ml/minute/gm) for EOM in primates (0.25 +/- 0.03), dogs (0.33 +/- 0.06), sheep (0.12 +/- 0.01), and geese (0.12 +/- 0.04) were determined using the Reference Sample Method with 15 +/- 3 micrometer 103Ru microspheres and complete cardiovascular monitoring. Mammalian EOM blood flow was significantly higher than that determined for other skeletal muscle; however, EOM blood-flow values for sheep were significantly lower than those for primates and dogs. No significant blood-flow differences were found between avian EOM and other skeletal muscle, reflecting the unique avian ocular anatomy. These data indicate that high blood flow is not a general property of EOM and suggest a relationship between functional ocular motility and blood flow.
本研究旨在定量测定具有广泛眼球运动能力的动物眼外肌（EOM）的血流量。使用参考样本法，采用15±3微米的103Ru微球体并进行完整的心血管监测，测定了灵长类动物（0.25±0.03）、狗（0.33±0.06）、绵羊（0.12±0.01）和鹅（0.12±0.04）眼外肌的血流值（毫升/分钟/克）。哺乳动物眼外肌的血流量显著高于其他骨骼肌；然而，绵羊眼外肌的血流值显著低于灵长类动物和狗。禽类眼外肌与其他骨骼肌之间未发现显著的血流差异，这反映了禽类独特的眼部解剖结构。这些数据表明，高血流量并非眼外肌的普遍特性，并提示功能性眼球运动与血流量之间存在关联。
