Case Report:
The case is reported of acute retinal necrosis with bilateral involvement due to Varicella Zoster virus in a 77 year-old man. Polymerase chain reaction (PCR) of aqueous humor was positive for Varicella Zoster virus (VZV). He developed a Kyrieleis' vasculitis a month after the starting treatment, when the PCR analysis was negative.
Discussion:
PCR is a quick and safe technique, with a high sensitivity and specificity of 97%, useful to diagnose and monitor the viral activity. The intervention must be urgent, due to the dramatically rapid evolution. Oral famciclovir oral is good alternative owing to its bioavailability.
