Herpes zoster (HZ) is an acute infection caused by reactivation of the latent varicella-zoster virus [1]. Herpes zoster ophthalmicus (HZO) occurs when inflammation spreads from the ganglion of Gasser to the ophthalmic branch of the trigeminal nerve. Optic neuritis, a very rare sequela of HZO [2-4], can occur simultaneously to the acute vesicular skin eruption or, more frequently, as a postherpetic complication. We report on a 74-year-old woman who presented with HZ optic neuritis 45 days after developing an incompletely treated bout of trigeminal HZ, characterized only by pruritus. It is important to value the non-specific manifestations of cutaneous HZ in the prodromal phase, so as to offer timely and appropriate treatment.
