Factors influencing prognosis of early vitrectomy on open globe injuries

Abstract:

Objective：To investigate factors influencing prognosis of early vitrectomy on open globe injuries. Methods：Clinical data of 25 patients with open globe injury who underwent early vitrectomy from July 2016 to June 2018 in our hospital were retrospectively analyzed，including visual acuity after injury，prognostic visual acuity，type of ocular trauma，division of ocular trauma，lens injury and/or dislocation，intraocular foreign body，vitreous hemorrhage，retinal detachment and influences of those factors on prognostic visual acuity. Results：Among 25 patients，10 eyes（40.0%） were injured in area Ⅰ，8 eyes（32.0%） injured in area Ⅱ and 7 eyes（28.0%） injured in area Ⅲ；11 eyes（44.0%） had visual acuity after injury≥0.05 and 14 eyes（56.0%） had visual acuity after injury<0.05；16 eyes（64.0%） had prognostic visual acuity≥0.05 and 9 eyes（56.0%） had prognostic visual acuity<0.05. Visual acuity after injury （P=0.017），trauma zone（P=0.013），vitreous hemorrhage（P=0.033） and retinal detachment（P=0.008） were important factors influenc－ing the prognostic visual acuity. Conclusion：After early vitrectomy，most of patients with open globe injury can achieve functional cure and anatomical cure. The better the visual acuity after injury is，the better the curative effect is. The prognostic visual acuity in area Ⅰ is obviously better than that in area Ⅲ. Vitreous hemorrhage and retinal detachment can significantly influence the prognostic vi－sual acuity.
