摘要
目的调查陕西省农村≥50岁老年人群中白内障盲的患病率和白内障手术覆盖率及其术后效果。方法2003年7～12月,采用整体随机分层抽样法在陕西省洋县、靖边县和富平县调查8500人,其中≥50岁人群2213人,所有受检人员均进行标准问卷调查及详细的眼科检查。视力检查使用LogMAR视力表分别对每只眼进行测量,晶状体混浊使用LOCSIII进行评价。结果≥50岁人群双眼盲和双眼低视力的患病率为2.1%,3.2%,其中女性患病率均高于男性(P<0.05)。由白内障造成的视力损伤患病率为6.9%,其中50岁人群中白内障造成的视力损伤患病率为2.4%,70岁人群则上升到17.9%,随着年龄的增加,患病率明显上升(P<0.01)。该人群中双眼视力<0.1的白内障手术负荷量为2.3%,手术覆盖率为37.0%,白内障盲的社会负担率为3.1%。在25只白内障手术眼中,实施ICCE手术眼10只,ECCE手术眼15只,无PHACO手术眼。其中ICCE术后矫正视力>0.3的占40.0%,ECCE术后矫正视力>0.3占53.3%。结论陕西省农村老年人群中由白内障造成的视力损伤还是一个比较严重的问题。该人群中白内障手术覆盖率还比较低,白内障术后效果没有达到病人的预期目标。
Objective The purpose of this study was to estimate the prevalence of blindness caused by cataract and cataract surgery among older adults in rural population in Shaanxi province. Method Visual acuity and eye examination were performed in 2003 from July to December in rural population in the Shaanxi province ~ random sample of 8,500 residents was identified and selected from the household registration databand. A total of 2213 subjects at least 50 years of age were invited to participant and 1775（80.2%） participated in the survey.An eye examination,including lens opacity,was conducted by ophthalmologist using the Lens opacity Classification System III（LOCSⅢ）.A stuctured questionnaire was used for data collection.Visual acuity was assessed with an illuminated IogMAR chart. Result The prevalence of bilateral blindness and bilateral low vision was estimated to be 2.1% and 3.2%,respectively.The prevalence of blindness in women was higher than that of men（P〈0.05）.Th e prevalence of visual impairment caused by cataract was 6.9%.There was a significant increase in the rate of visual impairment caused by cataract（p〈0.01） from 2.4% at 50 to 59 years of age to 17.9% at age 70 years or old.In those populations the burthen of cataract surgery with bilateral vision less 0.1 was 2.3%, and cataract coverage was 37.0%and cataract blindness burden was 3.1%.Among 25 eyes with cataract surgery, 10 eyes were performed ICCE and 15 eyes were performed ECCE,and no eyes were PHACO.The corrected vision after ICCE〉0.3 occupied 40.0%,and the corrected vision after ECCE〉0.3 occpied 53.3%. Conclusion Blindness,particular blindness related to cataract,continues to be a significant public health problem among the elderly in this population-based sample of rural Chinese.Among those population cataract coverage was low. Cataract surgery is reaching fewer than half of those who could benefit from it.
