- Abstract
Abstract Purpose To evaluate the efficacy of prophylactic vitrectomy for acute retinal necrosis. Methods The clinical charts of 17 patients (18 eyes) with acute retinal necrosis and no retinal break or rhegmatogenous retinal detachment (RRD) were retrospectively analyzed for the efficacy of prophylactic vitrectomy. The retinal necrotic lesions at the initial presentation were classified into three groups according to the lesion site as described by Holland: zone 1 (posterior pole; n = 3), zone 2 (midperiphery; n = 12), and zone 3 (periphery; n = 3). All patients were treated with intravenous antiviral therapy. Three zone 1 eyes and eight zone 2 eyes underwent prophylactic vitrectomy. Four zone 2 eyes and three zone 3 eyes did not receive prophylactic vitrectomy. Results All zone 1 eyes developed RRD despite prophylactic vitrectomy. Among the 12 zone 2 eyes, eight of the eyes that underwent prophylactic vitrectomy did not develop RRD, whereas three of the four zone 2 eyes without prophylactic vitrectomy developed RRD. All zone 3 eyes were cured with only antiviral medication. Conclusions Prophylactic vitrectomy is effective in preventing the development of RRD in eyes where necrotic lesions do not extend beyond the midperiphery (zone 2).
