视神经、视网膜等服组织对眼动脉血流的变化反应敏感，尤其是儿童，视神经、视网膜的发育与眼动脉血流的供应情况密切相关．获得眼动脉血流动力学的相关值对眼科临床工作有重要意义．成人眼动脉血流的正常值已有人统计、测定，但儿童眼动脉血流的正常值未见报道．为填补这一空 Optic nerve and retinal isobaric tissue is sensitive to changes of ophthalmic artery blood flow, especially the development of children, optic nerve and retina is closely related to the supply of ophthalmic artery blood flow. Obtaining ophthalmic arterial hemodynamics has important implications for clinical ophthalmology. The normal value of adult ophthalmic artery blood flow has been statistics, determination, but the normal value of children’s ophthalmic artery blood flow has not been reported. To fill this empty
