한국인 눈동맥 가지의 변이

Abstract

Branches of the ophthalmic artery were dissected and onserved under the surgical microseope in 80 side orbits of Korean adults, Branches of the aphthalmic artery were divided into seven types according to their artangement and their enbryology were discussed B type in the most common. order of branches medial podterior ciliary artery, central artery of retina, lateral. posterior ciliary, lacrimal, medial muscular, supraordital, posterior ethmoidal and anterior ethmoidal srtery(41.3％) The lacrimal artery originating from the middle meningeal aetery was observed only in types A,B and D and its incidence was 30％ over all. One variation was observed where a main ophthalmic arose from the middle meningeal artery and a leteral posterior ciliary artery arose from the internal caroud artery with no comminication between two: it happened due to disappearence of double segment of the embryonic arterial ring. In two sides a contral artery of the retina and a lateral posterior ciliary artery arose from another part due to intrasegmental division at the dorsal primitive ophthalmic artery Main branches at the first part were the central artery of retina and the lateral posterior ciliary; at the second part they were the lacrimal artery and the lateral muscular artery: and at the third were mainly medial muscilar, supraorbital and posterior and anterior and anterior ethmiodal arteries. But according to types, branches at certain parts varied. The first branch of the ophthalmic artery was the most common trunk of central artery of the retina, and medial pisterior ciliary artery than the central artery of retina. The incidence. the original site and the mode of origon pf branches were studied, and the results were discussed embryologically.
