Etiological factors and clinical outcomes in Non-Traumatic Non-Diabetec retinopathic vitreous hemorrhage

Abstract

Objective To analyze the etiological factors in non-traumatic non-diabetec retinopathic vitreous hemorrhage and to investigate the clinical outcomes of vitrectomy in such patients.Methods The etiologic factor and recovery rate of visual functions in a total of 174 patients (176 eyes) undergoing vitrectomy with follow-up records from March 2006 to July 2009 in our department were analyzed retrospectively.Results Vitreous hemorrhage was found in 73 eyes of retinal vein occlusion (RVO),25 eyes of Eales' disease,25 eyes of retinal hole or retinal detachment (RH/RD),22 eyes ofexudative age-related macular degeneration (EAMD),and 15 eyes ofpolypoidal choroidal vasculopathy (PCV),amounting to 90.9% of total eyes.The visual improvement rate after vitrectomy was more than 90%.Conclusions RVO,Eales' disease,RH/RD,EAMD and PCV are main causes of non-traumatic non-diabetec retinopathic vitreous hemorrhage.Vitrectomy is an effective way for vitreous hemorrhage.
