摘　　要：应用美国Ａｃｕｓｏｎ－１２８型彩色多谱勒声像仪，对正常人各年龄组１２３例（２４６只眼）的眼动脉血流速度进行测定。发现眼动脉收缩期峰值速度：右眼为３６．４４±８．３５ｃｍ／ｓ，左眼为３６．９４±１１．３０ｃｍ／ｓ。右、左眼及性别之间差异无显著性。各年龄组间，４１岁以上各组与以下各组间差异有显著性。提示４１岁可能是全身小血管老化过程的开始，为抗衰老提供参考。同时对急性闭角型青光眼发作期的１８只眼、临床前期１５只眼的眼动脉血流速度进行了检测。The authors measured the velocity of the ophthalmic arterial blood flow with color Doppler sonography(Acuson-128, USA)in 246 eyes of 123 normal persons to evaluate exactly the changes of the blood supply in all ischernic fundus diseases and provide the reliable reference basis for the clinic. The average velocity of the ophthalmic arterial flow of the normal in the maximum contraction period(peak systolic velocity, PSV)is respectively 36.44±8.35cm/sec on the right and 36. 94±11.30cm/sec on the left.There were no significant differences in PSV between the right and left eyes and between the male and female persons. We found that PSV of the ophthalmic artery in persons over 41 years old was significantly different from that in persons below that age,suggesting the age of 41 years old be the beginning of the senile process of systemic small blood vessels and providing a reference for anti-senility. In the mean time, the velocity of ophthalmic arterial blood flow was also evaluated in 18 eyes with the acute attack of acute angle-closure glaucoma and 15 eyes at pre-clinical stage.
