[Multifocal choroiditis associated with herpes zoster ophthalmicus. Apropos of a case]

Abstract

We describe a patient with multifocal choroidal lesions affecting the midperipheral fundus, with an atrophic and scattered punched-out pale aspect. Lesions were discovered seven months after an ipsilateral herpes zoster ophthalmicus. Fluorescein angiography findings exhibited a delay of choroidal injection and late moderate staining during the venous phase. The etiological arguments refer to a previous herpes zoster infection. The pathogeny would involve an occlusion of posterior ciliary arteries, lesions of posterior ciliary nerves and/or direct cytopathogenic involvement of chorioretina by neurotropic virus from ciliary ganglion.
