Abstract:

目的研究环孢霉素A(CsA)在青光眼滤过手术中的抗增殖作用。方法〖HTSS〗将20只中国白兔40只眼随机分成2组,一组为环孢霉素组,另一组为生理盐水对照组,2组均行小梁切除术,术中分别在结膜瓣下放置2%环孢霉素A、生理盐水棉片5min,在术后第1、7、14、30天观察眼压、滤过泡、角膜、眼底,并行光镜、电镜及增殖细胞核抗原(PCNA)检查。结果环孢霉素A组眼压控制多较理想,与对照组间的差异有统计学意义(P<0.05),大多数形成功能性滤过泡,光镜下见极少量纤维组织增生,电镜下见纤维细胞线粒体少,染色质功能不活跃,增殖细胞阳性率低,与对照组差异有统计学意义(P<0.05),且没有浅前房、视网膜损害等严重并发症。结论环孢霉素A在兔眼滤过手术中抗增殖作用好,安全性高。
