Abstract

A 22-year male presented 3 days after hammer-chiesel injury with limbal wound, vitreous hemorrhage and foreign body on orbital radiograph. Following primary repair of entry wound, on USG and CT orbit, it was found to be perforation injury with metallic foreign body in mid orbit lateral to optic nerve. At 1 week, 25 gauge pars-plana vitrectomy was performed at low infusion pressure. Two disc diameter linear exit wound was noted transecting infero-temporal arcade. After removal of vitreous incarceration, 1 mm chorioretinectomy was done surrounding the exit wound using endodiathermy probe at high power settings. Following fluid-air exchange, laser was done around chorioretinectomy site and silicone oil was injected for endotamponade. At 3 months follow-up, BCVA was 6/60 with retina attached and some fibrosis developing at exit wound. Early vitrectomy and chorioretinectomy decreased the risk of retinal incarceration, proliferative vitreoretinopathy and retinal detachment in this case.
