摘要
采用碳素墨水动脉灌注和苯浸渍透明研究了30例视网膜中央动脉的起点,经过和分支分布情况.视网膜中央动脉可发自眼动脉,亦可与内侧睫状后短动脉或与外侧睫状后短动脉共干发自眼动脉.按视网膜中央动脉的经过可分为眶内段、鞘内段和神经内段.观察了各段的分支及其与其它动脉分支之间的吻合情况.讨论了视网膜中央动脉对视神经血供关系的生理意义,为眼科临床提供了形态学基础.
This study was designed to investigate the origin,course,branches and distribution of the central retinal artery (CRA) in 30 cases after carbonic ink injection and transparence with benyol macerate.The CRA originated from the optic artery,or together with the medial or lateral short posterior ciliary artery.According to the course of the CRA,it could be divided into three parts:intraorbital,intravaginal and intraneural.We observed the branches of each part and their anastomosis with other branches of the optic artery.We discuss the physiological significance of the relationship between the CRA and the blood supply of the optic nerve in this paper,which provideds the morphology foundation for the study of the clinical opthalmology.
