Twenty-six eyes with intraocular foreign bodies (IOFB) and/or their sequelae were treated by pars plana vitrectomy and associated surgery. One-step removal of the IOFB in combination with pars plana vitrectomy resulted in early visual rehabilitation and minimal complications. Of 11 eyes with IOFB treated by primary vitrectomy at the time of IOFB removal 20/50 or better visual acuity was obtained in 10 (91%). Four of these eyes had retinal injury, 3 of which were successfully repaired without subsequent complication and with retention of good visual function. In 3 eyes IOFBs were not removed owing to chronic retinal encapsulation. These eyes continue to retain good visual acuity, and ERG studies show no evidence of retinal toxicity. Of 12 eyes in which vitrectomy was performed for sequelae of IOFB only 5 (41%) showed visual improvement better than 20/50. Only in 2 of 7 eyes with tractional retinal detachment could the retina be reattached. In cases of retinal injury primary vitrectomy, cryocoagulation, and scleral buckling are suggested for prevention of late traction retinal detachment.
26例伴有眼内异物（IOFB）和/或其后遗症的患者接受了玻璃体切除联合相关手术治疗。在眼内异物取出的同时行一期玻璃体切除术一步取出眼内异物，可实现早期视力恢复且并发症最少。在11例于取出眼内异物时接受一期玻璃体切除术治疗的患者中，10例（91%）获得了20/50或更好的视力。其中4例存在视网膜损伤，3例成功修复，无后续并发症且保留了良好的视功能。3例因慢性视网膜包裹而未取出眼内异物。这些患者的视力持续保持良好，视网膜电图（ERG）研究未显示视网膜毒性迹象。在12例仅因眼内异物后遗症而行玻璃体切除术的患者中，只有5例（41%）视力改善超过20/50。在7例牵引性视网膜脱离患者中，仅2例视网膜得以复位。对于视网膜损伤病例，建议行一期玻璃体切除术、冷冻凝固术和巩膜扣带术以预防晚期牵引性视网膜脱离。
