Incidence and Post-Operative Visual Outcome in Patients with Intraocular Foreign Body

Background: Intraocular foreign body is an important complication of ocular trauma, especially open globe trauma. It can cause a range of complications leading to severe visual impairment to permanent blindness. They are removed via Pars Plana Vitrectomy using either forceps, endomagnet, or both. Various management techniques and their impact on final visual outcomes are identified in this study. Objective: To study the various factors influencing the final visual outcome in cases of intraocular foreign bodies treated via pars plana vitrectomy and surgical removal of the foreign body. Study type, settings & duration: This retrospective descriptive study was conducted at the Department of Ophthalmology, Allied Hospital, Faisalabad from June 2019 to December 2020. Methodology: About 57 consecutive patients presenting to the Ophthalmology department, Allied Hospital Faisalabad with intraocular foreign bodies were included in this study. All the patients included, underwent pars plana vitrectomy and surgical removal of an intraocular foreign body. The final best-corrected visual acuity of patients was recorded on follow-up visits. Results: The mean age of the participants was 29, 54 (94.7%) were males while only 3 (5.3%) were females. Final visual acuity was significantly poor in patients with foreign bodies involving the retina (p-value: 0.001) and in patients who underwent pars plana vitrectomy and surgical removal of the intraocular foreign body later than 7 days after the trauma p ~0.012 (p <0.05). Conclusion: This study concluded that the final visual acuity is significantly better in cases where IOFB does not involve the retina..........
