摘　　要：目的:探讨正常眼压性青光眼与眼部血流的可能关系。方法:用彩色多普勒显像检测18例正常眼压性青光眼患眼的眼动脉和视网膜中央动脉血流情况,并与11例正常人对照。结果:正常眼压性青光眼患眼的眼动脉收缩期峰值流速(Vi_(max))减少、舒张末期流速(V_(mix))减少、搏动指数(PI)减低和阻力指数(RI)增大;视网膜中央动脉的RI与正常人比较差异也有显著性。结论:正常眼压性青光眼的眼部血流动力学异常和局部血管病变可能提示其发病机制。Purpose. To evaluate the correlation between normal tension glaucoma (NTG) and ocular blood flow. Methods.The blood flow of ophthalmic artery and central retinal artery were measured by Color Doppler imaging in 18 cases of NTG and 11 cases of normal person as control Results. There were significant differences in maxium velocity (Vmax)、 minium velocity (Vmin)、 pulsation index (PI) and resistance index (RI) of ophthalmic artery between 18 cases of NTG and the control. There was also significant difference in RI of central retinal artery between the two groups. Conclusion. The abnormality of ocular hemodynamics and local blood vessel of NTG may indicate its pathogenesis.
