To report basic epidemiological data concerning surgically treated childhood cataract in Sweden and Denmark.
Data were derived from the Paediatric Cataract Register (PECARE), a binational, web-based surgical register representing Sweden and Denmark. All children operated before 8 years of age between 1 January 2007 and 31 December 2013 were included. Age-specific prevalence per 100 000 population was calculated.
A total 574 operations in 213 boys (51.7%) and 199 girls (48.3%), altogether 412 children, were registered, the vast majority (n = 395/412; 95.9%) being individuals with congenital/infantile cataract. Of these 412, a total of 294 (147 boys and 147 girls) were Swedish and 118 (66 boys and 52 girls) were Danish. The age-specific prevalence of operated cataract in Sweden was 31/100 000 and in Denmark 28/100 000. In 454 of 574 eyes (79.1%), the cataract was dense. Altogether, 266 of 574 (46.3%) were operated during the first year of life, 193 during the first 12 weeks representing 33.6% of all operations. A primary intraocular lens (IOL) implantation was done in altogether 411 of 574 eyes (71,6%). In total, 210 unilateral cataract operations (210/574; 36.6%) were performed. Persistent fetal vasculature (PFV) was present in 64 of 193 (33.1%) of those with a congenital unilateral cataract. In 84 individuals (84/395; 21.3%) with congenital or infantile cataract, a coexisting disorder was found.
The age-specific binational prevalence of operated congenital/infantile cataract in Sweden and Denmark is 30/100 000. About half of the operations are performed within the first year of life, one-third within the first 3 months. In our study population, a primary IOL was implanted in the majority of cases.
报告瑞典和丹麦接受手术治疗的儿童白内障的基本流行病学数据。
数据来源于儿科白内障登记处（PECARE），这是一个代表瑞典和丹麦的基于网络的双边手术登记处。纳入了2007年1月1日至2013年12月31日期间所有8岁前接受手术的儿童。计算每10万人口的年龄别患病率。
共登记了574例手术，其中213名男孩（51.7%）和199名女孩（48.3%），共412名儿童，绝大多数（n = 395/412；95.9%）为先天性/婴儿性白内障患者。在这412名患者中，共有294名（147名男孩和147名女孩）是瑞典人，118名（66名男孩和52名女孩）是丹麦人。瑞典手术治疗白内障的年龄别患病率为31/10万，丹麦为28/10万。在574只眼中的454只（79.1%），白内障为致密性。总共574例中的266例（46.3%）在出生后第一年内接受手术，193例在前12周内接受手术，占所有手术的33.6%。574只眼中共有411只（71.6%）进行了一期人工晶状体（IOL）植入。总共进行了210例单侧白内障手术（210/574；36.6%）。193例先天性单侧白内障患者中有64例（33.1%）存在永存原始玻璃体增生症（PFV）。在84例（84/395；21.3%）先天性或婴儿性白内障患者中发现了并存疾病。
瑞典和丹麦手术治疗先天性/婴儿性白内障的双边年龄别患病率为30/10万。约一半的手术在出生后第一年内进行，三分之一在头3个月内进行。在我们的研究人群中，大多数病例进行了一期IOL植入。
