To determine the prevalence and subtypes of glaucoma in Vientiane Province.
We conducted a population-based study of 1264 participants aged ≥40 years of age from urban and rural areas of Vientiane Province. Data collection included Snellen visual acuity, slip lamp examination, tonometry, gonioscopy, dilated stereoscopic disc examination and perimetry. Glaucoma was categorised by clinical subtype.
The mean age of the 1264 participants was 57.6 years; 91.9% of eyes had a gradable disc. The prevalence of glaucoma of any category in at least one eye was 1.54% (95% CI 0.66% to 3.59%). The overall prevalence of primary open-angle glaucoma, primary angle-closure glaucoma and secondary glaucoma was 0.62% (95% CI 0.19% to 1.98%), 0.55% (95% CI 0.12% to 2.54%) and 0.37% (95% CI 0.07% to 1.86%); 12 (66.7%) of participants with glaucoma were at least unilaterally blinded by WHO definition.
The prevalence of glaucoma in the Vientiane Eye Study is relatively low compared with the prevalence reported in other studies from Asian regions; however, the median age in this study was low, reflecting the age group of the population and the rapid urbanisation occurring in the Lao People's Democratic Republic. Nevertheless, glaucoma remains a blinding disease in this population.
确定万象省的青光眼患病率和亚型。
我们对来自万象省城乡地区的 1264 名年龄≥40 岁的参与者进行了一项基于人群的研究。数据收集包括 Snellen 视力、裂隙灯检查、眼压测量、房角镜检查、散瞳立体视盘检查和视野检查。青光眼根据临床亚型进行分类。
1264 名参与者的平均年龄为 57.6 岁；91.9%的眼睛有可分级的视盘。至少一只眼患有任何类型青光眼的患病率为 1.54%（95%CI 0.66%至 3.59%）。原发性开角型青光眼、原发性闭角型青光眼和继发性青光眼的总体患病率分别为 0.62%（95%CI 0.19%至 1.98%）、0.55%（95%CI 0.12%至 2.54%）和 0.37%（95%CI 0.07%至 1.86%）；12 名（66.7%）青光眼患者至少按照世卫组织的定义单侧失明。
与亚洲其他地区的研究报告相比，万象眼病研究中的青光眼患病率相对较低；然而，该研究的中位年龄较低，反映了人口的年龄组和老挝人民民主共和国正在迅速城市化。尽管如此，青光眼仍然是该人群中的致盲性疾病。
