目的:调查中山市年龄相关性白内障患病的情况及白内障手术负荷量和患者自愿接受手术的情况,并制定相宜的干预政策,更好地开展本地区的防盲治盲工作。方法:采用整群抽样的方法对中山市东、西、南、北、中5个镇区50岁及以上年龄的常住户籍人群进行白内障流行病学的调查,对所有调查对象集中询问病史,进行视力检查,并采用裂隙灯显微镜检查晶状体是否混浊,依据白内障诊断标准,了解本地区白内障的患病情况。结果:在66034例受检者中,50岁及以上年龄的白内障总体患病率为46.71%,女性患病率高于男性,且随着年龄的增长,白内障患病率明显升高,白内障手术负荷量为15.83%,患者手术接受率为43.00%。结论:白内障手术负荷量较高,而患者自愿接受手术的情况较低,白内障防盲治盲工作仍是一项长期的工作,需制定相宜的干预策略,提高患者手术接受率。

AIM:To investigate the prevalence situation of age-related cataract, cataract operation load and the situation of patients voluntarily accept the operation in Zhongshan City, and to establish appropriate intervention policy in order to better carry out the work of prevention and cure blindness.METHODS:Cataract epidemiology investigation were performed in ≥50 year-old permanent population by cluster sampling method in east, west, south, north, center 5 townships of Zhongshan City. All subjects were examined history, visual inspection, slit-lamp microscope to check whether the crystal is muddy. Based on cataract diagnostic criteria, local prevalence of cataract was known.RESULTS:In 66 034 subjects, cataract overall prevalence rate of ≥50 year-old subjects was 46.71%. The female prevalence was higher than male, and with the growth of age, prevalence of cataract increased significantly. Cataract surgery load capacity was 15.83%, the surgery acceptance rate of patients was 43.00%.CONCLUSION:Cataract surgery load is high, while the situation of patients voluntarily accepting the operation is low. Cataract blindness prevention is a long-term work, making appropriate intervention strategies and improving the surgery acceptance rate of patients.
