• Purpose To determine the prevalence, types and awareness of glaucoma in a rural community in China and to examine possible ethnic variations. Methods The Yunnan Minority Eye Study was a multi‐ethnic community‐based eye survey using random cluster sampling strategies. 2133 Bai, 2205 Han and 2208 Yi Chinese aged 50 years or older participated in this study. Glaucoma including primary open‐angle glaucoma (POAG), primary angle‐closure glaucoma (PACG) and secondary glaucoma was defined based on the International Society of Geographical and Epidemiological Ophthalmology criteria. Results The overall age‐standardized prevalence of all glaucoma was 2.6% (95% confidence interval [CI]: 2.2–3.1%) in this population. It was 1.8% (95% CI: 1.1–1.9%) for POAG and 0.5% (95% CI: 0.9–1.6%) for PACG, respectively. Among 29 people with secondary glaucoma, 27 (93%) were blind in at least one eye. The presence of primary open‐angle glaucoma was associated with male gender (odds ratio [OR] = 2.94; comparing men with women), Yi ethnicity (OR = 2.27; comparing Yi with Han people), higher IOP (OR = 1.09 per mmHg increase), and the presence of myopia (OR = 1.84). Of the 212 participants with glaucoma, only 38 (18%) were aware of the disease and had been diagnosed previously as having glaucoma or suspected glaucoma. Patients who were better educated tended to be aware of the disease. Conclusions Significant ethnic difference in the prevalence of POAG was observed in this study. The low awareness of glaucoma highlights the pressing need to increase public awareness of this potentially blinding condition in rural China.
