Posterior sderal reinforcement for the treatment of choroidal neovascularization in degenerative myo-pla

目的观察后巩膜加固术治疗变性近视脉络膜血管新生的安全性和可行性。方法采用后巩膜加固术治疗变性近视脉络膜血管新生20例（20眼）。结果术后16眼最佳矫正视力较术前明显提高，术后屈光度和眼轴长较术前减少（P〈0．05）。光学相干断层成像技术（OCT）检查显示术后脉络膜水肿减轻、新生血管减小17眼，视网膜厚度较术前下降。结论后巩膜加固术治疗变性近视脉络膜新生血管疗效良好。

Objective To observe safety and efficacy of posterior scleral reinforcement in the treat- ment of choroid neovascularization in degenerative myopia. Methods 20 cases （20 eyes） of choroidal neo- vascularization of degenerative myopia underwent posterior scleral reinforcement operation. Results Post- operative best corrected visual acuity of sixteen eyes were improved obviously , the ocular axial length and re- fractive degree were reduced （ P 〈 0.05 ） . The OCT showed CNV shrinked, the choroidal edema and chroidal neovascularization decrease in 17 eyes. Conclusion Posterior scleral reinforcement in the treatment of cho- roidal neevaacularization of degenerative myopia plays a role of protecting the visual function.
