23 Gauge pars plana vitrectomy for the removal of retained intraocular foreign bodies

Abstract

BackgroundTo evaluate the morpho-functional outcomes and safety of transconjuctival 23-gauge pars plana vitrectomy(PPV) for removal of intraocular foreign bodies (IOFBs).MethodsA retrospective study of 36 consecutive cases (mean age; 34,2 ± 10,9 years (between 15 and 60), 27 M,9 F) of 23-G PPV for the removal of IOFBs during the period of April 2009 and December 2011 and followed 9,4 ± 6,4(2–27) months were conducted. Visual outcomes, slit lamp biomicroscopy, intraocular pressure (IOP), and posterior segment visualization by indirect ophthalmoscopy, A-B mode ultrasonography, and computed orbital tomography were performed for all cases. Main outcomes including anatomic and visual outcomes, and both intraoperative and postoperative complications were recorded.ResultsOf the 36 cases available for the study, the IOFBs (size range, 3 to 12 mm) could be removed in all eyes. Mean preoperative LogMAR BCVA was 1.44 ± 138 (range, 1.00 to 0.00) and mean postoperative LogMAR BCVA at final visit was 0,78 ± 0,98 (range, 1.00 to 0.00). (P = 0,007) Anatomic success was obtained in 97.2 % of eyes. 16 patients needed primary wound repair due to the leakage in insertion sites before the PPV, however remaining 20 cases were not. Fibrin reaction was seen in 8 (22.2 %) patients in early postoperative period, intraocular pressure elevation was detected in 12 (33.3 %) patients in which the silicone oil was used as an intravitreal tamponade, one patient with silicone oil tamponade developed band keratopathy and phthisis bulbi.Conclusions23-Gauge PPV is a feasible, effective approach in the surgical management of the patients with posterior segment intraocular foreign bodies.

RETRACTED: Good visual rehabilitation in a patient without traumatic cataract surgery after removal of a ferrous intravitreal foreign body by external magnetic extraction through a pars plana incision: A case report

“…The prognosis of traumatic eye injuries associated with IOFBs varies greatly depending on a number of factors, which include the time between trauma and IOFB extraction, initial visual acuity, entrance wound location, nature of IOFB, location of IOFB, preoperative retinal detachment, presence of intraocular hemorrhage, presence of endophthalmitis, and primary surgical repair combined with IOFB removal and the occurrence of postoperative complications [7]. PPV is the most common surgical approach for the removal of a posterior segment IOFB, as it provides direct viewing and controlled surgery [8][9]. The aim of the treatment is to restore ocular integrity and to obtain a good visual outcome.…”

Clinical characteristics and prognostic factors of posterior segment intraocular foreign body in a tertiary hospital

“…Pars plana vitrectomy can be the first choice for the patients with the IOFBs in the posterior segment, though magnetic suction from the sclera is still used in the non-developed areas. With advancement of the surgical facilities and the techniques, 23-gauge vitrectomy was commonly recommended for the posterior IOFBs on account of the less damages and rapid recovery [16]. Sometimes 25-gauge vitrectomy was also used in some cases.…”
