To identify clinical features and evaluate outcomes of vitreoretinal surgery in eyes with retained non-metallic and non-magnetic metallic intraocular foreign bodies (IOFBs).
Retrospective chart review. Thirty-two eyes (28 patients) with non-metallic and non-magnetic metallic IOFBs underwent removal of IOFBs with intraocular forceps, either via the pars plana in 30 eyes (93.9%) or a limbal approach in 2 eyes (6.25%). The main outcome measures were postoperative visual acuity, rate of retinal break formation, development of retinal detachment, and type of IOFB.
IOFBs were non-metallic in 22 eyes (68.7%) and non-magnetic metallic in 10 eyes (31.1%). The average follow-up period was 7.5 months. Overall, final visual acuity was 20/40 or better in 10 eyes (31.1%) and 5/200 to 20/50 in 10 eyes (31.1%). A higher incidence of retinal break formation posterior to the sclerotomy was seen with glass IOFBs (P = .02). Retinal detachment was observed preoperatively in 4 eyes (12.5%) and postoperatively in 2 eyes (6.25%).
Final visual outcome was independent of size and type of IOFB. Pars plana extractions may be associated with a higher rate of retinal break formation and subsequent retinal detachment, particularly with glass IOFBs.
识别伴有残留非金属及非磁性金属眼内异物(IOFBs)的眼睛行玻璃体视网膜手术的临床特征并评估其预后。
回顾性病历分析。32只眼(28例患者)伴有非金属及非磁性金属IOFBs,采用眼内镊取出IOFBs,其中30只眼(93.9%)经睫状体扁平部取出,2只眼(6.25%)经角膜缘入路取出。主要观察指标为术后视力、视网膜裂孔形成率、视网膜脱离的发生情况及IOFBs的类型。
22只眼(68.7%)的IOFBs为非金属性,10只眼(31.1%)为非磁性金属。平均随访时间为7.5个月。总体而言,10只眼(31.1%)的最终视力为20/40或更好,10只眼(31.1%)为5/200至20/50。玻璃IOFBs导致巩膜切开术后视网膜裂孔形成的发生率更高(P = 0.02)。术前4只眼(12.5%)观察到视网膜脱离,术后2只眼(6.25%)观察到视网膜脱离。
最终视力预后与IOFBs的大小和类型无关。经睫状体扁平部取出可能与视网膜裂孔形成及随后视网膜脱离的发生率较高有关,尤其是玻璃IOFBs。
