To evaluate visual and safety outcomes of 23-gauge (G) pars plana vitrectomy (PPV) with application of perfluorocarbon liquid (PFCL) for intraoperative protection of the macula during intraocular foreign body (IOFB) removal. Retrospective study of 42 patients who underwent 23 G PPV for IOFB removal from posterior segment with intraoperative PFCL application for the macula shielding. Collected data included corrected distance visual acuity (CDVA), size of IOFB, and complication rate. The mean follow-up period was 12 months. . The mean preoperative CDVA was 0.54 logMAR (SD 0.46), and the final mean CDVA was 0.68 logMAR (SD 0.66). All IOFBs were metallic with mean dimensions of 4.6 mm × 2.1 mm. Twenty-two IOFBs were removed through the corneal tunnel and 20 IOFBs through the sclerotomy. No intraoperative iatrogenic lesion of the macula was observed. As a tamponade, silicon oil was applied in 31 eyes, SF gas in 5 eyes, air in 4 eyes, and 2 eyes required no tamponade. Secondary retinal detachment was observed in 17% of cases, but at the end of the follow-up, all the retinas were attached. . PFCL application during PPV is a safe method of protecting the macula from unexpected falling of the metallic IOFB during its removal.
评估在眼内异物（IOFB）取出术中应用全氟碳液（PFCL）进行黄斑部术中保护的23号（G）玻璃体切割术（PPV）的视觉和安全性结果。对42例接受23G PPV进行后段IOFB取出且术中应用PFCL进行黄斑部遮挡的患者进行回顾性研究。收集的数据包括矫正远视力（CDVA）、IOFB大小和并发症发生率。平均随访期为12个月。术前平均CDVA为0.54 logMAR（标准差0.46），最终平均CDVA为0.68 logMAR（标准差0.66）。所有IOFB均为金属性，平均尺寸为4.6 mm×2.1 mm。22个IOFB通过角膜隧道取出，20个IOFB通过巩膜切开术取出。未观察到术中黄斑部医源性损伤。作为填塞物，31只眼应用硅油，5只眼应用SF气体，4只眼应用空气，2只眼无需填塞。17%的病例观察到继发性视网膜脱离，但在随访结束时，所有视网膜均复位。PPV术中应用PFCL是一种在金属IOFB取出过程中保护黄斑部免受意外掉落影响的安全方法。
