Effect and outcome of vitrectomy for treatment of open-globe injuries

Abstract

Objective To evaluate the clinical efficacy of vitrectomy surgery for open-globe injuries.Methods Retrospectively analyzed the data of patients with open-globe injuries treated from January of 2009 to May of 2012,except cases diagnosised as intraocular foreign body or traumatic endophthalmitis that need emergency vitrectomy.Results There are 104 eyes of 104 cases of open-globe injuries,been divided to two groups based on the time of vitrectomy after the injury,fifty-one patients received vitrectomy within ten days after the trauma,fifty-three patients received vitrectomy more than ten days after injury in other group,twenty-seven(53％) patients best corrected visual acuity(BCVA) improved more than three levels in the group that had a vitrectomy within ten days after the injuries,sixteen(31.4％) patients had traumatic proliferative vitreoretinopathy(TPVR) ; In the other group there were sixteen(30.2％) patients BCVA improved greatly,thirty-four patients had TPVR; Ten of fifty patients who appear TPVR had a poor prognosis,only three patients in fifty-four patients without TPVR had a poor prognosis;The incidence of TPVR was 63.3％ (31/49) in the group that trauma implicate the retina and choroid.The incidence of TPVR was 34.5％ (19/55)in the other group.Conclusion For patients with serious open-globe injuries of eyes,especially those retina and choroid injured the same time,in order to prevent the TPVR and other risk factors,they need a earlier vitrectomy.
