Coxsackievirus B4 as a cause of adult chorioretinitis.

Abstract

To describe the clinical manifestation and course of chorioretinitis presumed to be secondary to coxsackievirus infection in an adult. Case report documented by fundus photography and fluorescein angiography. Ophthalmoscopic examination of a symptomatic 34-year-old woman showed several cream-colored parafoveal spots at the level of the retinal pigment epithelium and similar, multiple confluent spots in the midperiphery of both eyes. Titers for coxsackievirus B4 demonstrated a fourfold rise between acute and convalescent sera. Coxsackievirus B4 is apparently a rare cause of chorioretinitis but nevertheless should be considered in the appropriate clinical setting.
