Efforts to understand more about the magnitude and distribution of glaucoma in Africa have usually been limited by reliance on clinic populations and inadequate definitions of glaucoma. Nonetheless, the surveys indicate that OAG is an important cause of blindness in Africa. The early stages of both types of glaucoma are often asymptomatic so patients often present late, particularly in developing countries. The challenges are with late presentation for diverse reasons one of which is low awareness and the silent nature of the disease. In Ghana, 19.4% of blindness is due to glaucoma. The prevalence of blindness and severe visual impairment was 0.74% and 1.07%, respectively. In rural Ghana, one-third (34.1%) of all glaucoma patients report bilaterally blind while half are uniocularly blind.
