Purpose: 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.
Method: Case report.
Results: 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.
Conclusion: The close association between the cutaneous eruption and the onset of visual symptoms suggests that the retinal lesion was caused by coxsackievirus infection.
