摘　　要：目的:探讨在玻璃体手术中应用前房维持器行眼内灌注的可行性。方法:实验组:一些眼球穿通伤患者如外伤性白内障合并有眼后段异物或眼后段损伤(如玻璃体混浊、出血),经前房维持器行眼内灌注做白内障摘除与玻璃体切除联合术,共20眼。标准对照组:行传统睫状体平坦部三切口闭合式玻璃体切除术的患者,共20眼。术中的玻璃体切割器均设定切割率为540次/min,抽吸力为150mmHg,测出术中灌注瓶高度分别在65cm时和在70cm时各眼的单纯抽吸状态下灌注速率、抽吸与切割状态下灌注速率;拔出玻璃体切除头和光导纤维,用巩膜钉封闭颞上方、鼻上方巩膜切口,测出术中灌注瓶高度分别在65cm时和在70cm时各眼的眼压。结果:灌注瓶高度为65cm时两组的单纯抽吸状态下灌注速率比较P=0.36、两组的抽吸与切割状态下灌注速率比较P=0.31;灌注瓶高度为70cm时两组的单纯抽吸状态下灌注速率比较P=0.13、两组的抽吸与切割状态下灌注速率差异比较P=0.18;灌注瓶高度为65cm时两组眼压比较P=0.56;灌注瓶高度为70cm时两组眼压比较P=0.45。结论:在一些眼球穿通伤患者如外伤性白内障合并有眼后段异物或眼后段损伤(如玻璃体混浊、出血)的玻璃体手术中使用前房维持器行眼内液体灌注是可行的。AIM： To evaluate the feasibility of using anterior chamber maintainer in operation on vitreous. METHODS： Experimental group： 20 eyeballs that had the penetrating injury, like traumatic cataract that combined with the eye-posterior trauma taken the cataract extraction associated the operation on vitreous. In this surgery the anterior chamber maintainer was used to infuse B.S.S; control group： there were 20 eyeballs that taken the the par plana vitrectomy. In this surgery the infusing ductus fixed in the incision of the sclera was used to infuse B.S.S., and the cutter rate was setted to 540 times per min and the aspiration＇s suction was setted to 150mmHg in vitreous cutter of every operation on vitreous. When the bottle height was 65cm and 70cm, the infusing rate under the state of aspiration or under the state of aspiration and excision of each eye were measured. The vitrectomy head and optical fiber were pulled out, closing the temples side with sclera nails, performing scleral incision above nose, measuring intraocular pressure in each eye when the infusion bottle height was 65cm or 70cm. RESULTS： When the infusion bottle height was 65cm, infusion rate was compared under the state of aspiration （P=0.36）, and under the state of aspiration and excision（P= 0.31）; when the infusion bottle height was 70cm, infusion rate was compared under the state of aspiration （P=0.13）, and under the state of aspiration and excision（P=0.18）;intraocular pressures between the two groups were compared when the infusion bottle height was 65cm（P=0.56）, and when the infusion bottle height was 70cm（P=0.45）. CONCLUSION： The use of the anterior chamber maintainer for infusing B.S.S in operation on vitreous is feasible.
