Posterior segment foreign body: Single step combined procedure i.e. Tear repair with vitrectomy with intra ocular foreign body (IOFB) removal

Abstract

Aim: To evaluate factors & compare results with OTS scoring in open globe injuries with IOFB managed with single step procedure Methods: Retrospective analysis of 22 cases with perforating injury with retained IOFB between January 2017- October 2018. Factors studied were nature of injury, nature of foreign body, time of presentation, & other raw score factors. Patients underwent tear repair with vitrectomy with IOFB removal as a single step procedure. Pre op factors affecting final outcome & post op visual acuity was analysed based on OTS scoring. Results: Mean follow up was 6 months. Males were pre-dominantly affected. 54.6% presented within 1 day compared to 45.4% who presented after 1 day of injury. 20/200-20/50 post op vision was attained in 87.5% in non-centre involving wound while 33.33% in centre involving wound. 66.6% patients had final vision in the range 1/200-19/200 or 20/200-20/50 in OTS -1, while its 80% in OTS -2 & 100 % in OTS -3 in vision range 20/200-20/50 & 20/40 Conclusion: Patients with wound of entry away from visual axis, non-metallic foreign body & no associated infection had better visual prognosis. Ocular trauma score in this study is better compared with international ocular trauma scoring system.
