目的 观察 2种方法治疗小梁切除术后无功能性滤过泡的远期疗效。方法 选择小梁切除术后无功能性滤过泡患者 10 5例 ,随机选择 5 5例 (A组 )在显微镜下作以穹隆为基底的结膜瓣 ,去除包裹、纤维性囊壁组织 ,用含 0 .4 g·L-1MMC的棉片在结膜下放置 5min ;5 0例 (B组 )在显微镜下用 5号针头潜行分离滤过泡后 ,在滤过泡旁 3mm结膜下注射MMC 0 .1mL。随访 2a后 ,观察眼压、滤过泡及并发症情况。结果 A组中成功 4 3例 ,有效 6例 ,无效 6例 ,总有效率为 89.0 9% ;I型滤过泡 32例 ,II型滤过泡 17例 ,III型滤过泡 6例。B组中成功 2 9例 ,有效 6例 ,无效 15例 ,总有效率为 70 .0 0 % ;I型滤过泡 19例 ,II型滤过泡 16例 ,III型滤过泡 15例。经统计学处理 ,2组之间成功率 (χ2 =4 .95 ,P <0 .0 5 )、总有效率 (χ2 =5 .97,P <0 .0 5 )的差别均有统计学意义。
Objective To observe the long-term effects of two methods for non-functional filter blebs after trabeculectomy.Methods One hundred and five cases with non-functional filter blebs were randomly divided into two groups,A(55 cases) and B(50 cases).Under the microscope,the buibar conjunctiva of the group A was divided from the limbus,resected hyperplastic fibre tissues,and put a piece of cotton contained 0.4g·L -1MMC under the buibar conjunctiva flap for 5 minutes.In the group B,after needling revision,0.1mL(0.2g·L -1)of MMC injection was injected subconjunctively at the 3mm around the blebs.Then postoperatively intraocular pressure(IOP),blebs and complications were observed for follow-up two years.Results In the group A,there were 43 cases with success,6 cases with effectiveness,6 cases with non-effectiveness,the total effective rate was 89.09%,and 32 cases with bleb I,17 cases with blebⅡ,6 cases wit blebⅢ.In the group B,there were 29 cases with success,6 cases with effectiveness,15 cases with non-effectiveness;and 19 cases with bleb I,16 cases with bleb Ⅱ,15 cases with bleb Ⅲ,the total effective rate was 70.00%.After chi-square test,the differences of success rate (χ 2=4.95,P<0.05) and total effectiveness rate(χ 2=5.97,P<0.05)showed significant in statistics between two groups.Conclusion The forward curative effect of being resected hyperplastic fibre tissues is better than needling revision on non-functional filter blebs.
