    Abstract:
    PURPOSE: To evaluate the clinical features, treatment, and visual outcome of patients with acute retinal necrosis (ARN). METHODS: The data of patients were retrospectively reviewed. Factors associated with visual loss and factors affecting the risk for retinal detachment (RD) development were evaluated. RESULTS: Twenty-four eyes of 24 patients (7 female/17 male, mean age 43.7 years, mean follow-up period 31.0 months) were included. In ocular fluid samples of 15 (83%) out of 18 eyes, polymerase chain reaction (PCR) tests were positive for herpes simplex virus (seven eyes; 39%), varicella zoster virus (six eyes; 33%), cytomegalovirus (one eye; 6%), and adenovirus (one eye; 6%). Central retinal occlusive vasculitis was observed in three (13%) eyes. Systemic antiviral therapy was given to all patients, and additional intravitreal ganciclovir was administered in seven eyes (29%). The most common complication was RD (46%). There was no statistically significant difference in the frequency of RD between herpes simplex virus- and varicella zoster virus-positive patients (p = .617). The rate of RD was similar in eyes undergoing prophylactic laser photocoagulation (LPC), eyes undergoing vitrectomy + LPC, and eyes not undergoing LPC (p = .237). The number of eyes with final visual acuity below 20/200 was significantly higher in eyes with RD than without RD (p = .047). CONCLUSION: Prophylactic LPC and vitrectomy did not show clear benefits in terms of preventing RD development. RD was the most common complication and a major factor for a poor visual prognosis.
