The survey was conducted in 3 out of the 18 administrative regions (aimaks); 4345 people aged > or = 40 years were examined, which represented 95.7% of the proposed sample. The prevalences of blindness and low vision in the sample were 1.5% (95% CI, 0.8-2.3%) and 8.1% (95% CI, 5.5-10.7%), respectively, from which the prevalences of blindness and low vision in the Mongolian population aged 40 years and older were estimated to be 1.4% and 7.7%, respectively. The prevalence of climatic droplet keratopathy was high (ranging from 15% to 50%) in this population, which included a large number of semi-nomadic cattle breeders, and was responsible for 7.2% of the blindness and 19.3% of the low vision. Cataract and glaucoma were the commonest blinding disorders, each accounting for around 35% of the blindness. Trauma accounts for a high proportion of those monocularly blind. Trachoma and xerophthalmia were not found.
该调查在18个行政区（aimaks）中的3个进行；对4345名年龄≥40岁的人进行了检查，占计划样本的95.7%。样本中失明和视力低下的患病率分别为1.5%（95%CI，0.8 - 2.3%）和8.1%（95%CI，5.5 - 10.7%），据此估计40岁及以上蒙古族人群中失明和视力低下的患病率分别为1.4%和7.7%。在这个包括大量半游牧养牛户的人群中，气候性小滴状角膜病变的患病率很高（15%至50%），导致7.2%的失明和19.3%的视力低下。白内障和青光眼是最常见的致盲疾病，各占失明病例的35%左右。外伤在单眼失明病例中占比很高。未发现沙眼和干眼病。
