• Thirteen patients with useful vision but suffering from uncontrollable neovascular glaucoma due to total angle closure were treated with modified filtering operations. Ten (77%) of the cases were controlled more than one year postoperatively. Most patients whose pressures were controlled maintained their preoperative visual acuities. These visual results appear to be better than those reported with cyclocryotherapy, where vision is usually lost despite satisfactory pressure control.
