Prognostic Factors in Vitrectomy for Posterior Segment Intraocular Foreign Bodies

Abstract

Delay in IOFB extraction, presence of intraocular hemorrhage, preoperative retinal detachment, primary surgical repair combined with IOFB removal are the predictive factors for anatomic failure.

Predictive factors and outcomes of posterior segment intraocular foreign bodies

“…The corneoscleral entry site indirectly reflected absence of retinal injury, which damaged the visual pathway, and absence of corneal scar that precluded good visual outcome. Poor final visual outcome (VA of less than 20/200) was reported previously in 17 to 50% of patients, 5,7 and in this study, 48.0% of the patients had poor final visual outcome, which demonstrated statistically significant correlation with the presence of relative afferent pupillary defect. However, the VA improvement observed within the first year after IOFBs removal could deteriorate from secondary complications during the second and third year, with stabilization occurring after the third year.…”

“…Good final visual outcome (VA of 20/40 or better) was reported in 30 to 71% of patients. 5,7,20 In this study, 36.4% of the patients had good final visual outcome, which demonstrated statistically significant correlation with the corneoscleral entry site (OR ¼ 18.36). The corneoscleral entry site indirectly reflected absence of retinal injury, which damaged the visual pathway, and absence of corneal scar that precluded good visual outcome.…”

“…1 Prognosis for vision in IOFBs was dependent on confluent predictive factors, as published by previous authors. [3][4][5] Because of the advancement in preoperative care and microsurgical technique during this era, several severely traumatized ophthalmic conditions can be managed successfully. The objectives of this study were to identify the predictive factors and evaluate the visual outcomes in posterior segment IOFB patients managed by pars plana vitrectomy (PPV).…”
