County Roscommon in the west of Ireland is a relatively remote rural area whose population of 55,000 is served by two community medical ophthalmologists and three optometrists. Eye surgical services are not available within the county. In order to assess the needs of the community for prevention of blindness from glaucoma, a simple random sample of the population of County Roscommon was taken for a community based glaucoma survey. A total of 2186 people over the age of 50 were examined which represented a 99.5% response rate. The high response rate was achieved by the community basis of the study and vigorous follow up of non-attenders. Intraocular pressure was measured using applanation tonometry, disc evaluation by both direct ophthalmoscopy and stereoscopic biomicroscopy, and visual field analysis using the Henson CFS 2000 and experimental computer controlled video perimetry. Diagnostic criteria were consistent with the preferred practice pattern of the American Academy of Ophthalmology. A crude prevalence of approximately 2% for primary open angle and normal tension glaucoma was found. The population profile of intraocular pressure showed a pattern which decreased with increasing age unlike the Framingham and Ferndale studies but similar to Japanese data.
爱尔兰西部的罗斯康芒郡是一个相对偏远的农村地区，当地55000人口由两名社区眼科医学专家和三名验光师提供服务。该郡内没有眼科手术服务。为了评估该社区预防青光眼致盲的需求，对罗斯康芒郡的人口进行了一次基于社区的青光眼简单随机抽样调查。共检查了2186名50岁以上的人，应答率为99.5%。高应答率得益于研究的社区基础以及对未参与者的积极随访。使用压平眼压计测量眼压，通过直接检眼镜和立体生物显微镜评估视盘，并使用Henson CFS 2000和实验性计算机控制视频视野计进行视野分析。诊断标准与美国眼科学会的首选实践模式一致。原发性开角型青光眼和正常眼压性青光眼的粗略患病率约为2%。眼压的人群分布呈现出一种随年龄增长而下降的模式，这与弗雷明汉和芬代尔的研究不同，但与日本的数据相似。
