Clinical analysis of retinal tear associated with vitreous hemorrhage

Abstract

Objective To discuss the treatment and efficacy of retinal tear associated with vitreous hemorrhage caused by acute posterior vitreous detachment.Methods 31 eyes with retinal tear with vitreous hemorrhage were included in the retrospective study.All cases were treated by binding up the eyes,semireclining position,hemostasis and enhancing the blood clearance subsequently at the early state.Laser photocoagulation or 20G pars plana vitrectomy were adopted depending on patients'condition.All cases had a followed-up for at least 12 months.Results 23 eyes underwent laser photocoagulation making for blocking retinal tears with clearance of vitreous hemorrhage within 1 week to 3 month,mean time (32.95 ± 12.61) days.Visual acuity of those cases were not influenced significantly.3 eyes occurred rhegmatogenous retinal detachment within 4 weeks underwent vitrectomy.Postoperative corrected visual acuity of 1 in 3 eyes was improved and no change in 2 eyes.5 eyes with no obvious vitreous hemorrhage absorption within 2 weeks to 4 weeks underwent vitrectomy.Postoperative visual acuity of 5 eyes were improved to be 0.3 ～ 0.6.Conclusion Retinal tear associated with vitreous hemorrhage caused by acute posterior vitreous detachment should be attended to.Early diagnosis with tears location and timely photocoagulation were the keys to win favorable result.Early vitrectomy also guaranted better visual acuity.
