目的 证明自体巩膜条翻转引流在青光眼小梁切除术后有保持滤过道畅通的作用。方法 健康成年家兔 2 5只 ,用自体巩膜条做为引流物 ,在巩膜瓣下引流 ,同一只家兔另一只眼做经典的小梁切除 ,进行滤过泡、眼压及组织学观察。结果 术后第 1～ 2周 ,实验组眼压低于对照组 ,差异无显著性 (P>0 .0 5 )。术后第 3～ 12周 ,实验组眼压明显低于对照组 (P<0 .0 5 )。术后第 2～ 7周 ,实验组功能性滤过泡存留比率明显高于对照组 (P<0 .0 5 )。结论 自体巩膜条翻转引流在小梁切除术后保持滤过功能、减少并发症方面有一定的作用
Objective To prove that autologous scleral fascia rollover drainage in the glaucoma after trabeculectomy has the effect of keeping the filtration tract clear. Methods Twenty-five healthy adult rabbits were treated with autologous scleral strips as drainage, drainage under the scleral flap, classic trabeculectomy with the other rabbit of the same rabbit, filtration bleb, intraocular pressure and histological observation . Results The intraocular pressure of the experimental group was lower than that of the control group at 1 ~ 2 weeks after operation, with no significant difference (P> 0.05). The IOP in the experimental group was significantly lower than that in the control group (P <0. 05) at 3 to 12 weeks after operation. At 2 to 7 weeks after operation, the functional filtration bleb retention rate in the experimental group was significantly higher than that in the control group (P <0.05). Conclusion Autologous scleral fascia rollover has a certain role in maintaining the filtration function and reducing the complications after trabeculectomy
