AIM:To study the effect of Ahmed glaucoma valve(AGV)implantation for neovascular glaucoma and prevention of its complications.METHODS:Eighteen patients underwent AGV implantation were summarized retrospectively.The visual acuity,intraocular pressure,postoperative complications and the effective rate were observed,the mean period of follow-up was 6-18 months.RESULTS:The postoperative best corrected visual acuities were stable in 11 eyes,improved in 5 eyes and dropped in 2 eyes.The success rate for intraocular pressure was 89% after the operation.The common postoperative complications included transient flat anterior chamber,high intraocular pressure and hyphema in early stage,fibrination in late stage.CONCLUSION:AGV implantation is one of the effective methods for neovascular glaucoma.
