An epidemiologic investigation on the prevalence of cataract in glass workers is presented. The study includes 209 workers over 50 years of age exposed to infrared (IR) radiation in the Swedish manual glass industry for 20 years or more, and 298 non-IR-exposed controls. The examination includes an evaluation of the individual IR-exposure and an ophthalmological examination with special reference to the lens. In IR-exposed workers 70 years of age and older there is a statistically significant increase of aphakia and of all types of cataract, subcapsular, cuneiform and nuclear, compared to the controls of the same age group. In the same age group the risk for an IR-exposed worker to have his vision reduced by cataract to 0.7 or less is 2.5 times as high as for non-exposed controls (95% confidence interval 1.4-4.4). The risk that he will have to be operated for cataract is 12 times as high (95% confidence interval 2.6-53). It is concluded, that the occupational IR-exposure of the glass workers accelerates the development of senile changes in the lens. All workers with a high exposure to IR radiation should be equipped with adequate eye protection.
本文介绍了一项关于玻璃工人白内障患病率的流行病学调查。该研究纳入了209名50岁以上、在瑞典手工玻璃行业中暴露于红外线（IR）辐射下20年及以上的工人，以及298名未暴露于IR的对照组。检查包括对个体IR暴露情况的评估以及针对晶状体的眼科检查。与同年龄组的对照组相比，70岁及以上暴露于IR的工人中，无晶状体以及所有类型的白内障（后囊下、楔形和核性白内障）的发生率在统计学上有显著增加。在同一年龄组中，暴露于IR的工人因白内障导致视力降至0.7及以下的风险是非暴露对照组的2.5倍（95%置信区间1.4 - 4.4）。其因白内障而必须接受手术的风险则高12倍（95%置信区间2.6 - 53）。研究得出结论，玻璃工人的职业性IR暴露会加速晶状体老年性变化的发展。所有高暴露于IR辐射的工人都应配备适当的眼部防护装备。
