A UNIQUE POSTERIOR SEGMENT PHENOTYPIC MANIFESTATION OF COXSACKIE VIRUS INFECTION
Retin Cases Brief Rep
PURPOSE: To report a posterior segment phenotypic manifestation of Coxsackie virus infection that has not been previously appreciated. METHODS: The clinical course and multimodal imaging findings, including spectral domain optical coherence tomography, fluorescein angiography, near infrared reflectance, and fundus autofluorescence of two patients with Coxsackie virus infections were documented. RESULTS: A neurosensory macular detachment was present in both patients on baseline examination. Fluorescein angiography demonstrated pooling within this lesion and spectral domain optical coherence tomography identified thickening of the retinal pigment epithelial band with variable degrees of attenuation of the ellipsoid zone and interdigitation zone. Fundus autofluorescence and near infrared reflectance imaging revealed multiple satellite lesions adjacent to the neurosensory detachment. These lesions were not seen on fluorescein angiography or color photography. Satellite lesions were hyporeflective on near infrared reflectance imaging and hyperautofluorescent on fundus autofluorescence imaging. The satellite lesions correlated with sites of ellipsoid disruption on spectral domain optical coherence tomography. Both patients were observed and their condition improved over the course of time. There was total resolution of satellite lesions, reconstitution of the ellipsoid zone and interdigitation zone, and return of retinal pigment epithelial thickness to the normal range. A bull's eye pattern of macular retinal pigment epithelial disturbance persisted on color and near infrared reflectance images, despite good visual acuity. CONCLUSION: Posterior segment Coxsackie virus infection may concurrently express the clinical characteristics of acute idiopathic maculopathy and multifocal retinitis. The visual prognosis in this variant is usually favorable. The multimodal imaging features that characterize this entity should be recognized to avoid confusion with other diseases that have a similar presentation.
