10 Glaucoma
Chapter 10: Secondary Angle Closure
Highlights
-
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.
