TNT 白内障已被确认为慢性三硝基甲苯中毒的临床特异性表现。近年来国内已发表了大量调查报告和有关TNT 白内障分期争论性文章,这一工业性损害普遍地被眼科学家和职业病学家重视。我们对某化工厂TNT 粉尘作业工人作了连续九年观察,每隔1—2年复查一次,共检查五次,详细的研究TNT 白内障临床动态变化。报告如下。检查方法眼部检查包括远、近视力,视野、外眼检查均用2%后马托品和新福林散瞳四次,每3—5分钟一次,瞳孔散大至7mm 时用裂隙灯显微镜在暗室检查角膜及晶状体。眼底镜检查眼底,绘图晶状体浑浊情况。临床分期参照北医三院眼科分期标准:根据晶状体浑浊的部位、程度、分布范围及皮质透明度等分为:前期、Ⅰ、Ⅱ、Ⅲ期。
TNT Cataract has been identified as a clinically specific manifestation of chronic TNT. In recent years, a large number of survey reports and controversial articles about TNT staging in TNT have been published in China. This kind of industrial damage is generally regarded by ophthalmologists and occupational disease scientists. We conducted a continuous nine-year observation of TNT dust workers in a chemical plant, reviewed them every 1-2 years for a total of five inspections, and studied the clinical changes of TNT cataract in detail. The report is as follows. Inspection methods Eye examination, including far, near visual acuity, visual field, external eye examination with 2% horsetail and new Fulin mydriasis four times, once every 3-5 minutes, dilated pupil to 7mm with slit lamp microscope Check the darkroom for cornea and lens. Fundus examination fundus, mapping lens turbid conditions. Clinical staging with reference to the North Medical Hospital ophthalmic staging criteria: According to the location of the lens turbidity, extent, distribution and cortical transparency is divided into: early stage, Ⅰ, Ⅱ, Ⅲ.
