Monofocal outer retinitis associated with hand, foot, and mouth disease caused by coxsackievirus.

Abstract

To report symptoms and signs from an otherwise healthy man with photopsia and monofocal outer retinitis occurring 3 days after the onset of hand, foot, and mouth disease. Case report. Ophthalmic examination revealed a single circumscribed area of pigment epithelial mottling in the left eye and a corresponding nonarcuate absolute scotoma. Fluorescein angiography demonstrated attenuation of the retinal pigment epithelium. Serologic tests at 1 month after the onset disclosed serum antibody to enterovirus. The close association between the cutaneous eruption and the onset of visual symptoms suggests that the retinal lesion was caused by coxsackievirus infection.
