Pellet gun injury as a source of ocular trauma; a retrospective review of one hundred and eleven cases

Abstract Purpose To report the demographic data, treatment methods, and outcomes among patients with pellet gun eye injuries. Methods This study was a retrospective review of all pellet gun eye injuries coming to Farabi Eye Hospital, a referral ocular trauma center in Iran, from February 2009 to November 2013. Patients' demographics, type of injury, choice of management, complications, and post-treatment visual acuity were recorded. Results One hundred eleven patients with a mean age of 25.7 ± 15.6 years entered the study. The most common age group was younger adults (16–45 years old) (61.3%). The mean uncorrected visual acuity after treatment was 2.05 (20/2240) ±1.5 logMAR. The most prevalent ocular zone was zone III (38.7%), and an intraocular foreign body was present in 97 patients (87.4%). Lid laceration and periocular tissue damage were present in 27 patients (24.3%). Lensectomy and vitrectomy were the most common treatment (31.5%). In most patients (87.4%), the injury was non-deliberate, and the most common time of hospitalization was the same day (45.0%). The only statistically significant indicator of post-treatment visual acuity was ocular trauma score (OTS) at admission ( P Conclusion Pellet gun injuries were more common among young male patients, and the only statistically significant indicator of post-treatment visual acuity was OTS at admission.
