空气作为填充物在眼内异物摘出术中应用的效果

The application efficacy of filtered air as the tamponade in the extraction of intraocular foreign bodies

目的评估过滤空气作为玻璃体填充物在玻璃体切除后段眼内异物摘出术中的应用效果。方法前瞻性非随机对照连续病例研究。我院2016年10月至2017年4月23G玻璃体切除联合后段眼内异物摘出术17例（17眼），根据病情选择过滤空气或硅油作为玻璃体腔填充物，比较两种手术的效果。结果共17例后段眼内异物，均一次摘出成功，过滤空气作为玻璃体填充物者7例，术后随访至少2个月，无视网膜脱离、玻璃体积血或感染性眼内炎等并发症。硅油作为玻璃体填充物者10例，2例硅油填充期间发生增生性玻璃体视网膜病变而导致视网膜脱离。结论后段眼内异物，视网膜裂孔较小而且无视网膜脱离者，以过滤空气作为玻璃体腔填充物可能是有效的。

Objective To evaluate the application efficacy of filtered air as the tamponade in the exatraction of posterior intraocular foreign bodies. Methods It was a prospective, nonrandom and consecutive cases study. Seventeen eyes of 17 patients with posterior segment intraoeular foreign bodies received vitrectomy combined with extraction of intraocular foreign bodies from Oct. 2016 to Apr. 2017. All cases were applied with filtered air or silicone oil according to the illness. The efficacy of two surgeries were compared. Results The foreign bodies of all cases were extracted in the first surgery. The filtered air was filled in 7 eyes and silicone oil tamponade in 10 eyes. The follow-up time was at least 2 months. The retinal detachment, vitreous hemorrhage and endophthalmitis weren＇ t found in eases with filtered air tamponade. The retinal detachment due to proliferative vitroretinopathy occurred in 2 eyes with silicone oil tamponade. Conclusion In cases of posterior segment intraocular foreign bodies patients with small retinal holes and no retinal detachment , filtered air as tamponade maybe effective and safe.
