The objective of this study is to describe the removal of retained intraocular foreign body (RIOFB) by bimanual pars plana vitrectomy through midline sclerotomy in phakic patients.
Four eyes with RIOFB and clear lens underwent microincision vitrectomy surgery. A chandelier illumination was placed through one of the existing ports. The foreign body (FB) was localized by direct visualization (intravitreal) or indentation (pars plana), stabilized using an intraocular magnet/FB forceps introduced through a midline sclerotomy and freed of vitreous from all sides using a vitrectomy cutter through the other port bimanually, reoriented along their long axis and extracted through the midline sclerotomy.
All four FBs were removed successfully without slippage or damage to the clear lens.
Chandelier illumination-assisted removal of FB through midline sclerotomy helps in easier localization, stabilization and removal, avoiding lens touch even in anteriorly located FBs such as at pars plana.
本研究旨在描述通过经中线巩膜切开的双手玻璃体切除术从眼内残留异物(RIOFB)中取出。
四例有 RIOFB 和透明晶状体的患者接受了微创玻璃体切除术。通过其中一个现有的端口放置了吊灯照明。通过直接可视化(眼内)或压痕(玻璃体平面)定位异物(FB),通过中线巩膜切开术引入的眼内磁铁/FB 夹稳定 FB,并通过另一个端口双手用玻璃体切割器从所有侧面游离玻璃体,沿其长轴重新定位并从中线巩膜切开术取出。
所有四个 FB 均成功取出,未发生滑脱或对透明晶状体造成损伤。
吊灯照明辅助经中线巩膜切开术 FB 的取出有助于更轻松地定位、稳定和取出 FB,即使在前部 FB (如在玻璃体平面)也避免接触晶状体。
