Systemic herpetic infection diagnosed by retinal biopsy.

We describe a patient with systemic lupus erythematosus who developed myelopathy, optic neuropathy, retinopathy, and aseptic meningitis unresponsive to immunosuppressive and antimicrobial therapy. Although cultures and brain biopsy were unrevealing, a Herpes virus was suggested by retinal biopsy. The patient recovered dramatically after institution of acyclovir therapy and optic-nerve-sheath decompression. This case demonstrates that herpetic retinitis can occur in an iatrogenically suppressed host and underscores the value of tissue diagnosis.
