To define the incidence and demographic characteristics of rhegmatogenous retinal detachment (RRD) requiring surgery in Korea.
Nationwide population-based retrospective study.
Patients who underwent surgery for RRD from 2007 to 2011 were retrospectively identified using the diagnostic code for RRD and the surgical codes for retinal detachment surgeries in the national claim database. The average incidence rate of RRD during the 5-year period was estimated using the population data of the 2010 Census in Korea.
A total of 24,928 surgically treated RRD cases were identified. The average incidence of surgery requiring RRD was 10.39 cases per 100,000 person-years [95% confidence interval (CI), 10.26-10.52). The incidence in men (11.32 cases per 100,000 person-years; 95% CI: 11.13-11.51) was significantly higher than that in women (9.47 cases per 100,000 person-years; 95% CI: 9.29-9.64) (p<0.001). The incidence of surgery requiring RRD showed a bimodal distribution across age groups, with one peak (28.55 cases per 100,000 person-years; 95% CI: 27.46-29.67) representing patients between 65 and 69 years of age and the second peak (approximately 8.5 per 100,000 person-years) representing patients between 20 and 29 years of age. The male-to-female ratio was approximately 1.0 for the peak-incidence age groups, whereas the ratio was higher for the other age groups.
The incidence of RRD in the Korean population was similar to that reported previously, with the peak incidence being lower than that in the Caucasian population. The age-specific RRD incidence pattern in Korea followed a bimodal distribution.
定义韩国需要手术治疗的孔源性视网膜脱离（RRD）的发病率和人口统计学特征。
全国性基于人群的回顾性研究。
使用国家索赔数据库中 RRD 的诊断代码和视网膜脱离手术的手术代码，回顾性确定 2007 年至 2011 年期间接受 RRD 手术的患者。使用 2010 年韩国人口普查的人口数据，估算 5 年期间 RRD 的平均发病率。
共确定了 24928 例接受手术治疗的 RRD 病例。需要 RRD 手术的平均发病率为每 100000 人年 10.39 例[95%置信区间（CI）：10.26-10.52]。男性（每 100000 人年 11.32 例；95%CI：11.13-11.51）的发病率明显高于女性（每 100000 人年 9.47 例；95%CI：9.29-9.64）（p<0.001）。RRD 手术的发病率在年龄组中呈双峰分布，一个高峰（每 100000 人年 28.55 例；95%CI：27.46-29.67）代表 65-69 岁的患者，第二个高峰（约 8.5 例/100000 人年）代表 20-29 岁的患者。高峰发病率年龄组的男女比例约为 1.0，而其他年龄组的比例较高。
韩国人群的 RRD 发病率与先前报道的相似，高峰发病率低于白种人群。韩国的年龄特异性 RRD 发病率呈双峰分布。
