Thirty-five consecutive cases of perforating ocular injuries with retained intraocular foreign body (IOFB) are examined in this retrospective study. Of the 35 cases with injuries, 30 (86%) were due to metallic foreign bodies. Of these, 25 (83%) involved foreign bodies of ferromagnetic origin. Magnetic extraction in combination with pars plana vitrectomy (or when possible, magnetic extraction alone) was successfully used to remove these foreign bodies. Even in cases where posterior vitrectomy is indicated, magnetic extraction allows good control of the foreign body during removal minimizing surgical trauma and the subsequent postoperative inflammatory response.
在这项回顾性研究中，对35例伴有眼内异物（IOFB）残留的眼球穿孔伤连续病例进行了检查。在这35例受伤病例中，30例（86%）是由金属异物所致。其中，25例（83%）涉及铁磁性来源的异物。采用磁性取出联合玻璃体切除术（或在可能的情况下，单独进行磁性取出）成功取出了这些异物。即使在需要进行后部玻璃体切除术的病例中，磁性取出也能在取出异物过程中很好地控制异物，将手术创伤及随后的术后炎症反应降至最低。
