本文就职业性TNT白内障的发病机制、临床表现及诊断等进行了综述,以为现行职业性白内障国家诊断标准的修改提供参考。职业性三硝基甲苯(TNT)所致晶状体损害的发生率、发生时间、进展率和进展程度与TNT接触的时间、浓度等密切相关。目前在TNT性白内障形成机制方面尚无肯定的结论。晶状体摄影能客观真实地反映出晶状体混浊的形态、范围、浓密程度,便于混浊范围的测量,有利于确定TNT白内障病变的分期与分级,可为职业性眼病及劳动能力的鉴定提供有力的证据。TNT白内障用药治疗难以取得明显的疗效。加强防护可以预防TNT白内障的发生。
In this paper, the pathogenesis, clinical manifestations and diagnosis of occupational TNT cataract were reviewed in order to provide reference for the revision of the current national diagnostic criteria for occupational cataract. Occupational TNT caused by the incidence of lens damage, occurrence time, rate of progress and degree of TNT exposure and time, concentration and so are closely related. At present, there is no definite conclusion about the mechanism of TNT cataract formation. Lens photography can objectively and truly reflect the morphology, range and intensity of opacity of the lens to facilitate the measurement of the opacity range, which is helpful to determine the staging and grading of TNT cataract. It can provide strong evidence for the identification of occupational eye diseases and labor ability. TNT cataract medication difficult to obtain significant effect. Strengthen the protection can prevent the occurrence of TNT cataract.
