目的:探讨化学伤的致伤物质种类、最容易发生化学伤的职业,眼部化学伤的严重性和伤后的并发症和视力预后。方法:通过病例回顾性研究,包括伤者的性别、年龄、种族、职业,探讨化学伤的致伤物质种类,就诊时视力,眼部化学伤的严重性和伤后的并发症和视力预后。结果:在75例患者中,90.3%为男性,84%在工作年龄范围(21～50岁);29.3%是工厂工人;52%碱烧伤;65.4%为制造厂和建筑工人;57.3%双眼受累;9.3%就诊时受伤眼视力<6/60;72%为I级;19.5%患者并发干眼症,角膜血管翳,角膜混浊,并发性白内障,继发性青光眼等;92%的伤眼最后视力是6/18或以上;6.2%伤眼失明。结论:虽然化学伤常常累及双眼,但多数患者伤情不严重,且视力预后较好。及时充分的冲洗可以缓解眼化学伤。适当的紧急处理可以减少长期的并发症和视力损害,但一些严重的化学伤可致盲。
OBJECTIVE: To investigate the types of chemical substances that cause injury, the occupational injury prone to chemical injury, the severity of eye chemical injury, post-injury complications and visual acuity prognosis. Methods: Retrospective study of cases, including the sex, age, race and occupation of the wounded, to explore the types of injury substances of chemical injury, visual acuity, severity of ocular chemical injury and post-injury complications and visual prognosis. RESULTS: Of the 75 patients, 90.3% were male and 84% were in the working age range (21-50 years); 29.3% were factory workers; 52% alkali burns; 65.4% were foundry and construction workers; 57.3% ; 9.3% of injured eye sight at visit <6/60; 72% of grade I; 19.5% of patients with dry eye, corneal angina, corneal opacity, complicated cataracts, secondary glaucoma; 92% of the injured eyes last Visual acuity was 6/18 or more; 6.2% of eyes were blind. Conclusion: Although chemical injuries often affect both eyes, most patients are not seriously injured, and the prognosis is good. Full and timely flushing can relieve eye chemical injury. Proper emergency treatment can reduce long-term complications and visual impairment, but some serious chemical injuries can be blinding.
