目的回顾性分析对外伤性黄斑孔行玻璃体切除联合内界膜剥除治疗的结果。方法分析本院2004年7月～2005年5月期间收治外伤性黄斑孔病人8例8眼,均进行闭合式玻璃体切除、吲哚青绿辅助下的视网膜内界膜剥除及过氟化碳眼内填充术。观察黄斑孔愈合和视功能恢复情况。结果8例均为全层黄斑孔。术前视力范围CF/30cm～0.2,低于0.01者3眼,0.01～0.1者3眼,0.1以上者2眼。挫伤直接造成黄斑孔3眼,陈旧伤、伴随黄斑前膜等改变者5例5眼。8例均顺利剥除内界膜。随访3m～6m,1眼因发生增殖性视网膜病变而再次手术,其余7眼(87.5%)黄斑孔闭合。术后视力范围眼前数指～0.5。视力<0.01者1眼,0.01～0.1者2眼,0.1～0.3者1眼,0.3以上者4眼,较术前明显提高(P<0.01)。结论玻璃体切除联合内界膜剥除及气体填充能有效促进外伤性黄斑孔闭合、提高视力。
Objective To retrospectively analyze the results of vitrectomy and internal limiting membrane ablation in traumatic macular hole. Methods Eight patients (8 eyes) with traumatic macular hole were treated in our hospital from July 2004 to May 2005. All patients underwent closed vitrectomy, and the indocyanine green-assisted retinal detachment and perfluorocarbon eye Filling technique. Observation of macular hole healing and visual function recovery. Results 8 cases were full-thickness macular hole. Preoperative visual acuity range of CF / 30cm ~ 0.2, less than 0.01 in 3 eyes, 0.01 ~ 0.1 in 3 eyes, more than 0.1 in 2 eyes. Contusion caused directly macular hole 3, old injury, accompanied by changes in the pre-macular membrane in 5 cases 5 eyes. 8 cases were successfully stripped of the inner limiting membrane. Follow-up 3m ~ 6m, 1 eye because of proliferative retinopathy and reoperation, the remaining 7 eyes (87.5%) macular hole closed. Postoperative visual acuity before the number refers to ~ 0.5. The visual acuity was less than 0.01 in 1 eye, 0.01 to 0.1 in 2 eyes, 0.1 to 0.3 in 1 eye and 0.3 in 4 eyes, which was significantly higher than that before operation (P <0.01). Conclusions Vitrectomy combined with the removal of inner limiting membrane and gas filling can effectively promote the closure of traumatic macular hole and improve the visual acuity.
