Isolated Optic Chiasmal Neuritis Secondary to Varicella-Zoster Virus Infection

Abstract

A 49-year-old woman without contributory medical history presented with zoster in the left-sided second cervical dermatome, and underwent oral valaciclovir at 3000 mg/day. Five days later, bitemporal hemianopia developed. Corrected visual acuities were spared, and funduscopic findings demonstrated no abnormalities in both eyes. Varicella-zoster virus (VZV) viremia was proved by the polymerase chain reaction test. Cerebrospinal fluid examination findings were normal. Cranial and orbital magnetic resonance imaging demonstrated no abnormalities. Thereafter, under 7 days of intravenous aciclovir at 1500 mg/day, bitemporal hemianopia gradually improved. This is a first reported case of isolated optic chiasmal neuritis secondary to VZV infection.
