为探讨玻璃体切割术在治疗儿童眼外伤中的作用和效果，对３１例（３１眼）年龄１２岁以下儿童眼后节外伤行玻璃体切割手术的效果进行了回顾性分析。３１眼中６眼为单纯玻璃体切割，其余联合巩膜环扎、外加压、或气液交换或ＳＦ６硅油内充填，其中１５眼联合晶体切割。结果：２２眼（７０．９７％）手术成功，其中锐器伤成功率为８０％，钝伤５０％，爆炸伤７１％，眼内炎７５％；外伤性视网膜脱离９眼，手术复位率３３．３３％；晶体切割眼手术成功率６６．６７％。结论：玻璃体切割术对儿童眼外伤具有重要治疗价值；外伤性视网膜脱离是眼外伤手术失败的主要原因；晶体切割可能是评估眼外伤玻璃体切割手术预后的指标之一。
To investigate the role and effect of vitrectomy in the treatment of ocular trauma in children, retrospective analysis was performed on the effect of vitrectomy on 31 cases (31 eyes) of children under 12 years of age undergoing ocular trauma. Among the 31 eyes, 6 eyes were simple vitrectomy. The rest were combined with scleral cerclage and external compression or gas-liquid exchange or SF6 silicone oil filling. Among them, 15 eyes combined with vitrectomy. Results: Surgical operation was successful in 22 eyes (70.97%), of which the successful rate of sharp injury was 80%, the blunt injury was 50%, the blast injury was 71% and the endophthalmitis was 75%. The traumatic retinal detachment was 9 and the rate of operation was 33 .33%; the success rate of crystal cutting eye surgery was 66.67%. CONCLUSION: Vitrectomy is an important therapeutic value for children with ocular trauma. Traumatic retinal detachment is the main reason for the failure of ocular trauma. Crystal cutting may be one of the indicators to evaluate the prognosis of vitrectomy for ocular trauma.
