Primary open-angle glaucoma (POAG), by far the most common form of glaucoma, currently afflicts more than 2 million Americans, more than half of whom probably don't know they have it. Asymptomatic in the early stages, it gradually and progressively reduces the visual field and leads to blindness if untreated. Elevated intraocular pressure is believed to play a role, yet some people with normal pressure develop POAG. There is no single diagnostic test; screening and diagnosis involve periodic comprehensive eye evaluations. Treatment is aimed at delaying onset, slowing progression, and preserving vision.
原发性开角型青光眼（POAG）是迄今为止最常见的青光眼类型，目前折磨着超过200万美国人，其中一半以上可能不知道自己患有此病。在早期阶段没有症状，它会逐渐并持续地缩小视野，如果不治疗会导致失明。眼内压升高被认为起了作用，但一些眼压正常的人也会患上POAG。没有单一的诊断测试；筛查和诊断需要定期进行全面的眼部评估。治疗旨在延缓发病、减缓病情进展并保留视力。
