玻璃体手术在后段眼内异物及其外伤性视网膜裂孔中的应用

Micro-vitreoretinal surgery for posterior segment intraocular foreign bodies associated traumatic retinal tears

目的探讨现代显微玻璃体手术在治疗眼后段眼内异物及其外伤性视网膜裂孔中的应用。方法对48例(48眼)眼内异物,包括磁性异物28例,非磁性异物20例,常规行玻璃体切除手术治疗、内路异物摘出、剥除异物床区玻璃体后皮质、眼内光凝及封闭视网膜裂孔。临床随访评估手术效果及并发症。结果48例(48眼)均摘出异物,视力改善或不变者44例(91.67%),视网膜脱离复位47例(97.92%)。结论眼后段眼内异物及其外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生性玻璃体视网膜病变的危险因素。

Objective To investigate the application of the vitrectomy and clinical characters for posterior segment intraocular foreign bodies associated traumatic retinal tears. Methods 48 cases who were suffered from intraocular foreign bodies, including magnetic foreign bodies 28 cases, nonmagnetic foreign bodies 20 cases, underwent routine vitrectomy via the third aisle of plana of ciliary body and treated PVR by intraocular laser or filler, according to patient＇s conditions. The mean following - up period in these patients was 12 months, and their effects and complications were analysed. Results The posterior segment intraocular foreign bodies were removed in 48 cases. Postoperative visual acuity was improved or remained unchanged 44 cases （91.67%）, reattachment retina 47 cases （97.92%）. Conclusions We chose vitrectomy for treating posterior segment intraocularforeign bodies associated traumic retinal tears. It is important that the predictable or prognostic dangenous factors what are traumatic lens cortex, vitreous haemorrhage, pathologic vitreous, covered tissues of forgien bodies, posterior vitreous cortex are sectioned and removed.
