目的 探讨儿童眼外伤继发青光眼的病因及其在外伤青光眼中的发生率 ,作为外伤后继发青光眼的早期诊断依据。方法 回顾分析了 89例儿童眼外伤后继发青光眼的临床资料 ,探讨了继发育光眼的原因、发生时间及与眼外伤的关系。结果 儿童眼球顿挫伤后继发青光眼与外伤性白内障 ,超过 180°范围的房角后退 ,虹膜明显损伤和晶状体异位有高度一致性。四种原因中的二种存在于所有病例中。儿童眼球穿通伤后继发青光眼与粘连性角膜白斑 ,可见的晶状体损伤或晶状体异位有关 ,集中于晶状体虹膜膈的损伤 ,而引起小梁网明显的功能损伤。结论 儿童眼外伤的正确处理 ,密切随访 ,观察眼压 ,尽可能早的预防不必要的视力损害。
Objective To investigate the etiology and the incidence of glaucoma secondary to ocular trauma in children with traumatic glaucoma as the basis for the early diagnosis of secondary glaucoma after trauma. Methods The clinical data of 89 children with secondary glaucoma after traumatic brain injury were retrospectively analyzed. The causes, the occurrence time and the relationship with ocular trauma were discussed. Results Children with glaucoma secondary to traumatic cataract after glaucoma, the angle of more than 180 ° retreat, the obvious iris damage and ectopic lens highly consistent. Two of the four causes are present in all cases. Children with traumatic eye injury secondary glaucoma and adhesive leukoplakia, the visible lens damage or lens ectopic, focusing on the lens iris diaphragm injury, causing significant damage to the trabecular meshwork. Conclusion The correct treatment of ocular trauma in children, follow-up, observe the intraocular pressure, as early as possible to prevent unnecessary visual impairment.
