Racial differences seen in the risks of open-angle, narrow-angle, and normal-tension glaucoma. The investigators (published in Journal of Ophthalmology) found that the OAG prevalence rate for Asian Americans (6.52%) was higher than that of non-Hispanic whites (5.59%), and similar to Latinos (6.40%). Relative to other races, the prevalence rates of NAG and NTG were significantly higher among Asian Americans (3.01 and 0.73%, respectively) relative to other races. Asian Americans had an increased risk of OAG, NAG, and NTG compared with non-Hispanic whites. Vietnamese, Pakistani, and Chinese Americans had higher risks of NAG; whereas, Japanese Americans had an increased risk of NTG compared to non-Asian Americans.
