本文利用经颅超声多普勒扫描仪（ＴＣＤ）对视神经萎缩（外伤性）的患、健眼眼动脉血流速度进行检测，且探讨其与睫状后动脉之间的关系以期探讨此病的发病机制，为临床合理治疗提供资料。结果表明：外伤性视神经萎缩患眼与配对的正常眼之间眼动脉血流速度无明显差异（Ｐ＞０．０５），中心固视组眼动脉血流速度增高占６０％，血流速度降低的占４０％。偏心固视组血流速度增高及降低的均占４４．４％，无变化的占１１．１％，患眼眼动脉血流速度与后睫状动脉灌注压之间无显著的直线相关关系（ｒ＝０．０４６６８，Ｐ＞０．０５）。
In this paper, transcranial ultrasound Doppler scanner (TCD) of optic nerve atrophy (traumatic), healthy eye artery blood flow velocity was measured, and explore its relationship with the posterior ciliary artery in order to explore the disease Pathogenesis, to provide information for clinical rational treatment. The results showed that there was no significant difference in the velocity of ophthalmic artery between traumatic optic atrophy and matched normal eyes (P> 0.05), and the rate of ophthalmic arterial blood flow was increased by 60% in central fixation group and the blood flow velocity was decreased Accounted for 40%. Eccentric fixation group, blood flow velocity increased and decreased accounted for 44.4%, no change accounted for 11.1%, eye artery blood flow velocity and posterior ciliary perfusion pressure was no significant linear correlation ( r = 0.04668, P> 0.05).
