上海市北新泾地区孔源性视网膜脱离的流行病学调查

Epidemiology survey of rhegmatogenous retinal detachment in Beixinjing districts, Shanghai

目的 了解孔源性视网膜脱离 (retinaldetachment,RD)的年发病率 ,以及孔源性RD发生的危险因素。方法 采用自制调查表 ,对 1996年 1月至 1999年 12月间上海市北新泾地区 10 8132人群调查资料进行分析。了解孔源性RD的年发病率及孔源性RD发生的危险因素。结果 1996年 1月至 1999年 12月间新发孔源性RD患者 6 1例 (6 1只眼 ) ,男性 2 9例 ,女性 32例。年发病率分别为1996年 11 3/ 10万、1997和 1998年均为 14 1/ 10万及 1999年为 17 6 / 10万。发病眼屈光度数≥ - 6 0 0D者占 4 1 0 %。结论 1999年孔源性RD的年发病率明显高于 1996年。男女间无差异。高度近视与视网膜脱离的发生有关。

Objective To investigate the recent incidence and related risk factors of rhegmatogenous retinal detachment (RD) in Chinese people Methods This incidence survey was based on 108 132 persons in Beixinjing districts, Shanghai, P R China Rhegmatogenous RD patients came from inpatient, outpatient service data and the local health net databank composed of health data of 97 5% of all local residents A contrast group was set up The previous population data can be used to estimate the whole and specific incidence of rhegmatogenous RD Some factors relevant to rhegmatogenous RD incidence were found by comparing the patient group and the contrast group Results In Dec 1996 to Dec 1999, 61 cases with rhegmatogenous RD newly happened The patients were 29 males and 32 females The annual incidences of rhegmatogenous RD in these 4 years were 11 3/10 5, 14 1/10 5, 14 1/10 5 and 17 6/10 5 respectively, and the average annual incidence was 14 4/10 5 (95% confidence interval 10 0-18 6) There was a high incidence of rhegmatogenous RD in persons older than 40 years, especially between 40 and 59 When compared with the contrast group, the proportion of high myopia (more than -6 00D) was significantly higher in rhegmatogenous RD patients group ( P <0 001) Conclusions The annual incidence of rhegmatogenous RD of local Chinese population in these 4 years is increasing It is strongly associated with high myopia and age, but not with gender
