摘要

Orbital Foreign Body (OFB) is a complication that can occur in orbital trauma. Penetration of an air gun pellet (as a foreign body) into orbit that has penetrated the orbital cavity and is lodged in it, can cause severe complications and damage to the orbital cavity; even result in blindness.Aim: To compare the visual outcome of patients with air gun pellet injury who underwent C-arm guided extraction with OTS predictive value.Materials and Methods: Thirty patients with orbital pellet injury were surgically treated with C-Arm fluoroscopy. The data were studied retrospectively and it included demographic data, the number of pellets, complete eye examination findings, post-traumatic (pre-operative) visual acuity and post-operative visual acuity and post-traumatic ocular complications. The statistical analysis was performed using SPSS version 16.0 for Windows.Results: Most of the patients were men (27 patients/90%), with an average age of 29.03±15.54 years. Sixteen cases (53.33%) involved left orbit. Six patients (20%) experienced pre-operative visual acuity of No Light Perception (NLP), as well as visual acuity of ≥20/200. Follow-up was performed two months after the retrieval of pellets in the orbital cavity. There were no significant differences in the pre-operative vision (2.04±1.07), compared to the post-operative vision 2.07±1.13 with a p-value of 0.937. In addition, there were no patients that had surgical complications, needed secondary, additional surgeries, and significant differences between the pre-operative and post-operative visual acuity.Conclusion: C-Arm guided extraction of the OFB does not affect the patients’ visual acuity, so the method is safe to extract the foreign metal objects (pellets) in the orbital cavity. OTS predictive value might not be applicable for the OTS injury due to gun pellets.
