目的探讨三硝基甲苯白内障的临床特点、诊疗及发病与工种、工龄的关系。方法对抚顺市职业病防治院2004年6月~2008年9月收治的62例TNT白内障病例资料进行回顾性分析。结果长期接触TNT可致慢性中毒,主要损害眼晶状体,造成中毒性白内障。接毒工龄越长,TNT粉尘浓度越高,TNT白内障患病率也越高。结论 TNT白内障治疗目前尚无特效措施,脱离接触后仍可继续发病,应以预防为主,采取切实有效的防护措施。
Objective To investigate the clinical features of trinitrotoluene cataract, diagnosis and treatment and its relationship with the type of work and length of service. Methods The data of 62 TNT cataract cases treated in Fushun Occupational Disease Prevention and Treatment Hospital from June 2004 to September 2008 were retrospectively analyzed. Long-term exposure to TNT can cause chronic poisoning, the main damage to the lens of the eye, causing toxic cataracts. The longer the poisoning service life, the higher the TNT dust concentration, the higher the TNT cataract prevalence. Conclusion There are no effective measures for TNT cataract treatment at present, and the disease can continue to develop after the contact with TNT. Therefore, prevention should be the main method and practical and effective protective measures should be taken.
