The causes of neovascular glaucoma included：diabetic retinopathy（25 eyes）,and retinal vein occlusion（20 eyes）.All patients received preoperative IVR combined with postoperative PRP. The mean best-corrected visual acuities（BCVA）were converted to the logarithms of the minimum angle of resolution（log MAR）for the statisitical analyses.Intraocular pressure（IOP）,the log MAR BCVA and surgical complications were evaluated before and after surgery.The follow-up period was 12 mo.RESULTS：A total of 39 cases showed complete regression of iris neovascularization at 7d after injection,and 6 cases showed a small amount of residual iris neovascularization. The success rates were 81.8% and 82.6% at 12 mo after trabeculectomy and AGV implantation,respectively. In the trabeculectomy group,the log MAR BCVA improved at the last follow-up in 14 eyes,remained stable in 6 eyes and decreased in 2 eyes. In 4 cases,slight hyphemas developed after trabeculectomy. A shallow anterior chamber developed in 2 cases and 2 vitreous hemorrhages. In the AGV group,the log MAR BCVA improved in 14 eyes,remained stable in 5 eyes and decreased in 4 eyes. Slight hyphemas developed in 3 cases,and a shallow anterior chamber in 3 cases. The mean postoperative IOP was significantly lower in both groups after surgery（F=545.468,P〈0.05）,and the mean postoperative log MAR BCVA was also significantly improved（F=10.964,P〈0.05）with no significant difference between two groups.CONCLUSION：It is safe and effective to treat NVG with this combined procedure,and we found similar results after IVR＋AGV implantation＋PRP and IVR＋trabeculectomy＋PRP in eyes with NVG.展开更多
