摘要
Schlemm 氏管是房水排出系统中重要环节之一,是原发性开角青光眼发病的关键部位,对其结构与机能的进一步研究是十分必要的,关于Schlemm 氏管(以下简称S管)血液充盈情况,迄乏专题论及,本文对此进行了观察与分析,以期对青光眼的诊断与治疗起到应有的作用。对象与方法检查对象:军人、干部、职工及其家属,共756人(均检查单眼)。其中男性477人,
After investigating 756 eyes’blood engorgment in Schlemm’s Canal (SC),we found thatwhether there is blood engorgment in SC has close relations to the intraocular pressure andobstruction in SC.The result of non-pressure examination shows:the blood engorgment inSC occurred in varying degrees in 208 eyes whose intraocular pressures are equal to or higherthan 10 mmHg.40.6% of 101 eyes with the intraocular pressure of 11—15mmHg developedblood engorgment in SC.26.4% of 95 eyes with the intraocular pressure of 16—20 mmHgdeveloped blood engorgment in SC.5.9% of 189 eyes with the pressure of 21—25mmHgdeveloped blood engorgment in SC.Only3.1% of 163 eyes with the pressure equalto or higher than 26mmHg developed a little blood engorgment in SC.Among the 756 eyes,466(61.6%)developed no blood engorgment in SC.After the pressure examination,the blood engorgment occurred in different degrees in the SC of 183 eyes.Besides the intraocular pressure,the blood engorgment has relations to the functional ob-structio SC.Under the certain pressure,the obstruction was removed and the blood flowinto the Canal.There were 281 eyes which always had no blood engorgment in SC.All theseeyes were the primary open angle glaucoma which were unable to be satisfactorily controlledwith medicine.This may be the irreversibility of the organic obstruction in SC.
