Cataract prevalence in Bulgaria is a subject of current registration and of research studies. Our report deals with three basic sources: national statistics data, epidemiological study on cataract incidence, and clinical observation on risk factors. In 1985, 7.9 cataract cases per 1,000 population (over 15 years) have been registered. Cataract extractions increased from 6,972 (1980) to 8,050 (1984). Cataract prevalence study on 2.5 representative samples during the 1970 census in Bulgaria demonstrated 3.6% for urban and 2.5% for rural populations for 1 year of observation. The data showed a 10-fold increase when additional ophthalmologic examination of a given sample had been performed. The clinically based study of cataract characteristics and risk factors includes about 600 patients for a 1-year period. In this report the data according to sex and age distribution, type of cataract and the presence of systemic disease have been presented.
保加利亚的白内障患病率是当前登记和研究的课题。我们的报告涉及三个基本来源：国家统计数据、白内障发病率的流行病学研究以及危险因素的临床观察。1985年，每1000人口（15岁以上）中有7.9例白内障病例登记在案。白内障摘除手术从1980年的6972例增加到1984年的8050例。1970年保加利亚人口普查期间对2.5个代表性样本进行的白内障患病率研究表明，在1年的观察期内，城市人口患病率为3.6%，农村人口患病率为2.5%。当对给定样本进行额外的眼科检查时，数据显示患病率增加了10倍。基于临床的白内障特征和危险因素研究在1年期间纳入了约600名患者。本报告列出了按性别和年龄分布、白内障类型以及全身疾病情况划分的数据。
