Chapter 10: Secondary Angle Closure
Secondary angle closure can occur in a variety of settings, including anterior segment neovascularization and inflammation and after surgery.
Secondary angle closure can be divided into types with pupillary block or without pupillary block.
Detection of iris and angle neovascularization requires careful observation with the slit lamp and gonioscopy.
Control of neovascular glaucoma has dramatically improved with the use of anti–vascular endothelial growth factor (anti-VEGF) therapy and, when combined with panretinal photocoagulation, can often obviate the need for surgical intervention.
It is important to ask patients presenting with acute bilateral angle closure about the use of drugs, including topiramate, that can induce secondary angle closure.
