Abstract

Purpose:

We aimed to analyze the visual prognosis and clinical characteristics of acute retinal necrosis according to the initially involved zone and extent.

Study design:

Retrospective, consecutive, cross-sectional study.

Methods:

We retrospectively reviewed acute retinal necrosis patients who were treated with systemic antiviral treatment, and assessed the visual prognosis of acute retinal necrosis following antiviral treatment based on the initially involved zone and the extent of acute retinal necrosis at the time of diagnosis. Moreover, we evaluated whether prophylactic laser photocoagulation had preventive effects on retinal detachment.

Results:

A total of 43 eyes from 35 patients with acute retinal necrosis were included. Eyes with zone I involvement/extensive retinal lesions showed poor visual prognosis (logMAR: 1.17 ± 0.97 vs 0.49 ± 0.81; p = 0.014) and a higher incidence of retinal detachment (9/30 (30.0%) vs 0/13 (0%); p = 0.039) after treatment. Retinal detachment was observed in 20.9% of cases, and its incidence was significantly lower in eyes that had undergone prophylactic laser photocoagulation.

Conclusion:

The overall visual prognosis of acute retinal necrosis is poor and can be determined at the time of diagnosis. Prophylactic laser photocoagulation exhibits preventive effects with regard to the development of retinal detachment. Therefore, laser photocoagulation should be actively considered in eyes with extensive retinal lesions to prevent retinal detachment and thus eventually improve the overall visual prognosis of acute retinal necrosis.
