摘要
目的 研究眼动脉的起始、走行、分支和分布,为眼科临床提供参考。方法 对23例成人头颅标本眼动脉进行解剖。结果 667%的眼动脉起自颈内动脉,333%的眼动脉来自颈内动脉和脑膜中动脉并相互吻合。其主要分支包括睫状后动脉、视网膜中央动脉、泪腺动脉等。结论 眼动脉主要来自颈内动脉和脑膜中动脉,视网膜中央动脉全部来自颈内动脉,表明视网膜的血供与颅内血供密切相关。
ObjectiveTo provide anatomic data basis for clinic ophthalmology,the origin,course,branches and distributions of ophthalmic artery were further investigated.Methods23 skulls of human cadavers were irrigated with red latex and fixed in formalin.Then the roof of the orbit were opened and 45 ophthalmic arteries were carefully studied within the orbit.Some arteries were measured.Results67 7% ophthalmic artery arose from the internal carotid artery,33 3% ophthalmic artery arose from both the internal carotid artery and the middle meningeal artery,but in two cases the main distribution of blood came from the middle meningeal artery.According to the relation to the optic nerve,the intra orbital course of ophthalmic artery were divided into three parts.The main branches of ophthalmic artery included posterior ciliary artery,central retinal artery,lacrimal artery.ConclusionThe ophthalmic artery mainly comes from the internal carotid artery and the middle meningeal artery.Most of the origin site of branches were located on the “Angle”,the second part and “Bend” in the ophthalmic artery.All the central retinal arteries coming from internal carotid artery indicated blood supply of retina is closely related to blood supply of intra cranium.
