Abstract

Propose:Intra-ocular foreign body (IOFB) injuries refer to a foreign body present inside the interior of the globe. There is increasing IOFB morbidity in modern life. Intra-ocular foreign bodies may be removed by pars plana vitrectomy.
Patients and Methods:The present study was a case series prospective interventional study conducted on 34 patients who underwent pars plana vitrectomy for IOFB removal during the period from November, 2019 to October, 2020, and attending to the outpatient and emergency unit of Mansoura Ophthalmic Center, Mansoura University. The patients were examined then scheduled for through anterior segment approach.
Results:The mean age of the studied patients was 34.94±10.946years. The patients(94.1%) were males. Most of the studied patients were at occupational exposure(73.5%), The results showed that most of IOFBs in the studied patients were metallic(64.7%), while 35.3% were non-metallic. The mean value of initial BCVA was 0.05±0.081 that improved at 1 week after operation to the mean value of 0.13±0.121,and then continue to improve in the follow-up visits to 0.16±0.156 in the 2nd visit after 3weeks, 0.19±0.176in the 3rd visit after 8 weeks and 0.24±0.223 in the 4th visit after 12weeks. There were 2cases of raised IOP(5.9%),1case ended with macular scar(2.9%),corneal edema was persistent in one case(2.9%),and PVR was noted in 5 cases(14.7%).
Conclusion:IOFB removal by PPV through anterior segment technique was effective, safe, with minimal complications, and Better visual outcome. Improvement of the final BCVA can be predicted by foreign body size, impaction site, initial visual acuity, afferent pupillary defect, Ocular trauma score.
