Abstract:

Objective    To investigate the clinical effect of glaucoma valve implantation on various refractory glaucomas. Methods    23 patients (23 eyes) with refractory glaucoma who underwent glaucoma valve implantation were divided into two groups according to glaucoma types and treatment methods: group A included 14 patients (14 eyes) who had neovascular glaucoma and underwent glaucoma valve implantation and retinal photocoagulation; group B included 9 patients (9 eyes) who had other refractory glaucomas and underwent glaucoma valve implantation and mitomycin C treatment. The visual acuity，intraocular pressure and complications were recorded, and the operation success rate was calculated. Results    The average intraocular pressure of two groups was obviously lower after operation than before operation(P<0.05). The visual acuity was improved in 8 eyes(57.14%) of group A and 6 eyes(66.67%) of group B 6 months after operation. There was no serious complication in all patients. The operation success rate was 85.71%（12/23) in group A and 88.89%（8/9） in group B. Conclusion    Glaucoma valve implantation is ideal treatment for refractory glaucoma，which can decrease intraocular pressure and increase operation success rate.
