The clinical observation for the treatment of acute retinal necrosis by vitrectomy

Objective To probe the effectiveness and the selection of operating juncture for the treatment of acute retinal necrosis (ARN) by vitrectomy.Methods Eleven eyes were treated with vitrectomy,7 eyes were accompanied by serious vitreous turbidity,2 had local retinal detachment,2 had whole retinal detachment and retinal holes.Endophotocoagulation were carried out in all cases.Results Eight months to 3 years after the operation,9 of the 11 eyes had retinal attachment,2 eyes with retinal detachment before operation had recurrent retinal detachment after removal of silicone and had no light feeling.The 9 successful eyes had kept FC/30cm and up visual acuity,in which 4 had 0 1 visual acuity,3 had 0 2 visual acuity.Conclusions Selscting adequate juncture to carry out vitrectomy for those serious ARN cases can avoid the occur or development of retinal and keep effective visual acuity.
