Epidemiology and Demographics
Primary open-angle glaucoma (POAG) poses a significant public health problem. The estimated prevalence of POAG in the United States in individuals older than 40 years is 1.86% (95% confidence interval, 1.75%–1.96%), based on a meta-analysis of population-based studies. Applied to data from the 2000 US census, this percentage translates to nearly 2.22 million Americans affected.[1] The number of POAG patients is estimated to increase by 50%, to 3.36 million in 2020.
The World Health Organization (WHO) undertook an analysis of the literature to estimate the prevalence, incidence, and severity of the different types of glaucoma on a worldwide basis. The data collected predominantly in the late 1980s and early 1990s, it was estimated the global population of persons with high IOP (>21 mm Hg) to be 104.5 million.[2] The incidence of POAG was estimated at 2.4 million persons per year. Blindness prevalence for all types of glaucoma was estimated at more than 8 million persons, with 4 million cases caused by POAG. Glaucoma was theoretically calculated to be responsible for 12.3% of blindness. This makes glaucoma the second leading cause of blindness worldwide, following cataract.
