【摘要】 目的:评价在全视网膜镜辅助下行玻璃体切除术摘取眼后节异物的效果。方法:回顾性分析2008-01/2010-01采用玻璃体切除术的28例30眼眼后节异物患者,全视网膜镜辅助直视下取出异物,视网膜脱离或裂孔者行重水置换,眼内光凝、巩膜外冷凝、硅油或C3F8填充处理,眼内炎者术毕球内注入万古霉素。结果:患者30眼一次全部取出异物,成功率100%(不包括眶内异物)。术后视力提高22眼(73%),不变5眼(17%),下降3眼(10%)。术后视力>0.02或数指/1m者18眼(即脱盲率60%)。术中发现视网膜脱离11眼,一次复位9眼(一次复位率82%)。结论:在全视网膜镜辅助下行玻璃体切除手术是摘取眼后节异物的有效方法,能提供宽广清晰的视野,提高患者的视力改善率。更多还原

【Abstract】 AIM:To evaluate the effects of panretinal mirror-assisted vitrectomy for removing foreign body from posterior segment.METHODS:We retrospectively analyzed 28 patients 30 eyes with posterior segment foreign bodies from January 2008 to January 2010,performed vitrectomy,removed foreign body under direct vision with panretinal mirror assisted,retinal detachments or breaks were treated with heavy water replacement,intraocular photocoagulation,scleral condensation,silicone oil or C3F8 filling,vancomycin injection for endophthalmitis postoperatively.RESULTS:All of 30 eyes,the foreign body of each eye was extracted for one time;the success rate was 100%(not including intraorbital foreign body).Best-corrected visual acuity increased in 22 eyes(73%);unchanged in 5 eyes(17%);decreased in 3 eyes(10%).Visual acuity >0.02 or finger count/1 meter in 18 eyes(literacy rate of 60%).During the operation,we found 11 eyes with retinal detachment,9 eyes were restorated one time(restoration rate 82%).CONCLUSION:With the assistance of panretinal mirror,vitrectomy for removing foreign body from posterior segment is an effective method,which can provide a wider and clearer vision to increase the improvement rate of visual acuity.更多还原
