铅的毒作用中,其靶器官之一就有视觉系统。急性或慢性铅中毒能引起不同程度的视功能损害。近年,由于生产技术提高,劳动条件改善,职业性铅中毒的发生率普遍下降,严重铅中毒的比例显著减少。目前,国外对于长期低浓度铅接触所致的“无症状性”铅中毒的眼部改变的研究,特别是对生长期儿童的眼部改变的研究,已日益受到人们的重视。本文就国外有关铅的眼部毒作用的实验和临床研究资料作一综述,供参考。
Among the toxic effects of lead, one of its target organs has a visual system. Acute or chronic lead poisoning can cause varying degrees of visual impairment. In recent years, due to the improvement of production technology, improvement of working conditions, the incidence of occupational lead poisoning generally dropped, and the proportion of serious lead poisoning decreased significantly. At present, researches on ocular changes of “asymptomatic” lead poisoning caused by long-term exposure to low concentrations of lead in foreign countries, especially eye changes in growing children, have attracted more and more attention. This article reviews the experimental and clinical research data on the toxicity of lead in the eye abroad for reference.
