A nation-wide survey was performed to estimate the frequency and distribution of Vogt-Koyanagi-Harada's disease (Harada's disease hereinafter). A questionnaire was mailed to the departments of ophthalmology in hospitals with at least 200 beds. The response rate was 489 out of 1,077 institutions, or 45.4%. The annual prevalence was estimated to be 15.5 per million and the incidence was 6.5 per million, based on the number of reported cases and the response rate per prefecture. It was estimated that 1,800 patients were treated for this disease annually and that there were about 800 new cases. Geographical distribution showed no special characteristics such as these seen with Behçet's disease. The results of the analysis of 1,833 cases showed that females were slightly more affected than males, with an age distribution on first visit which showed a peak in the fourth decade and with the median age being 42.3 years.
开展了一项全国性调查，以评估葡萄膜大脑炎（以下简称原田病）的发病率和分布情况。向至少拥有200张床位的医院眼科部门邮寄了调查问卷。在1077家机构中，有489家回复，回复率为45.4%。根据各都道府县上报病例数及回复率，估计年患病率为百万分之15.5，发病率为百万分之6.5。据估计，每年有1800名患者接受该病治疗，约有800例新发病例。地理分布未显示出如白塞病那样的特殊特征。对1833例病例的分析结果显示，女性受影响略多于男性，初诊时的年龄分布在40岁左右出现峰值，中位年龄为42.3岁。
