Combination Surgery for Management of Perforating Eye Injury With Retained Magnetic Intraorbital Foreign Body

Abstract

The objective of this study was to evaluate the feasibility and safety of vitrectomy combined with magnetic intraorbital foreign body (IOrFB) removal in the patients with perforating eye injury and retained magnetic IOrFBs. A consecutive series of 7 patients with perforating eye injury and retained magnetic IOrFBs were included to perform secondary combination surgery (vitrectomy combined with IOrFB removal) after primary repair. Clinical data such as age, sex, hours and cause of injury, site and size of penetrating wound and IOrFB, involved intraocular tissues, surgical intervention, interval between surgeries, length of follow-up, anatomic recovery, visual outcome, and so on were recorded. Except for an unsuccessful IOrFB removal in case 6 in which IOrFB was finally extracted after 3 months, the remaining 6 cases had been operated on successfully both in vitrectomy and IOrFB removal. All the cases resulted in not only anatomic recovery but also good visual outcomes. No complications occurred. Seven cases revealed flat retina after silicone oil removal at a 3- to 12-month follow-up. Final best correct visual acuity equal to or better than 0.05 and 0.2 were 6 (85.7%) and 4 (57%) cases, respectively, and only 1 case was without improvement because of macular involvement. A combination surgery of vitrectomy with IOrFB removal is a highly efficient and safe procedure for the management of perforating eye injury with magnetic IOrFB. Prompt and proper management, such as preoperative exact localization of IOrFB, thoroughly cleaning of vitreous hemorrhage, complete sealing of retinal hole, and so on, is crucial for the successful achievement.
