Primary open angle glaucoma (POAG) is the most common form of glaucoma, with at least 80 million people affected globally1. However, the prevalence of POAG varies widely in different parts of the world and between ethnicities1-3, with high rates of POAG in Africa and Latin America, and much lower rates in the Middle East, for example. In contrast, angle closure glaucoma (ACG) is much more common in Asia than elsewhere in the world1-3. The prevalence of glaucoma also increases dramatically with age, particularly from 65 years old. POAG is also more common in males, whereas NTG and ACG are more common in females1.
