Vision Problems in the U.S. estimated the population with glaucoma to be 2.7 million in 2010. This number is estimated to be 2.86 million in 2014, and will increase by nearly 50% to 4.3 million by 2032 and by more than 90% to 5.5 million by 2050.
Fuchs and associates 23 found that glaucoma patients' mean time as members of the Danish Association of the Blind (DAB) from admission to death (indicating time with blindness) decreased over time from about 16 years in 1960 to approximately 6 years in 1970.e have access to data on a large and representative part of all diagnosed glaucoma patients in our catchment area (population 305 000). This gave us the opportunity to study the lifetime risk of low vision and blindness in patients with open-angle glaucoma as well as the time with visual impairment from glaucoma.
