Blackford BG, Justin GA, Baker KM, et al. - Researchers conducted this retrospective review to determine the risk factors associated with developing proliferative vitreoretinopathy (PVR) from combat ocular injuries in U.S. service members. Ocular injuries were analyzed in U.S. service members wounded from 2001 to 2011 during Operation Enduring Freedom and Operation Iraqi Freedom, and all PVR cases were examined from these. Eight hundred ninety eyes of 651 U.S. service members have been assessed. In total, 76 eyes (8.5%) of 66 patients developed PVR.PVR occurs often in combat trauma and is a major cause of poor final VA. In patients with PVR and RD, major risk factors for PVR development were injuries caused by an IOFB, macular hemorrhage, or unsuccessful repair.
