Purpose: To report the results of multimodal imaging of West Nile virus chorioretinitis.
Methods: Three patients with West Nile virus chorioretinitis were evaluated by color fundus photography, fluorescein angiography, enhanced depth optical coherence tomography, indocyanine green angiography, and fundus autofluorescence.
Results: Imaging results demonstrate outer retinal and retinal pigment epithelial involvement with inner retinal sparing.
Conclusion: Multiple fundus imaging modalities used during the diagnosis of West Nile chorioretinitis are consistent with outer retinal and pigment epithelial changes, suggesting outer retina and retinal pigment epithelium as the primary sites of ocular involvement.
