目的分析现代玻璃体手术治疗眼后段眼内异物及其创伤性视网膜裂孔和临床特点。方法修复角、巩膜伤口,玻璃体手术,内路摘出异物,剥除异物床区玻璃体后皮质,眼内光凝,封闭视网膜裂孔。临床随访评估手术疗效及并发症。结果38例(38眼)均摘出异物。术中共查见55个视网膜裂孔,裂孔成因分别为:①异物直接刺伤,异物弹跳二次撞击刺伤;②贯通伤发生裂孔;③不合理选择外路反复磁吸异物且失败。结论眼后段眼内异物及其创伤性视网膜裂孔应选择玻璃体联合手术,尽量去除诱发外伤性增殖性玻璃体视网膜病变的危险因素。
Objective To analyze the clinical effect of modern vitrectomy for intraocular foreign bodies and traumatic retinal breaks in the posterior segment of the eye. Methods Repair angle, scleral wound, vitreous surgery, intracranial extraction of foreign body, removal of foreign body cortex vitreous, intraocular photocoagulation, closed retinal tears. Clinical follow-up evaluation of surgical efficacy and complications. Results 38 cases (38 eyes) were foreign body. A total of 55 retinal holes were examined. The causes of the holes were as follows: ① direct foreign body stab wounds, foreign body bounce secondary stab wounds; ② penetrating wounds; ③ unreasonable choice of foreign bodies repeatedly magnetic foreign bodies and failure. Conclusion Intraocular foreign bodies and traumatic retinal tears in the posterior segment of the eye should be selected vitrectomy combined with surgery to remove the risk of traumatic proliferative vitreoretinopathy as possible.
