Multimodal Imaging of Macular Serpiginous Choroidopathy From Acute Presentation to Quiescence

The authors report imaging findings in a case of macular serpiginous choroidopathy (MSC). Near-infrared reflectance (NIR), fundus autofluorescence (FAF), and spectral-domain optical coherence tomography (SD-OCT) were performed on a 25-year-old man presenting with decreased visual acuity and a blind spot in his left eye. Fundus examination revealed a yellow subretinal infiltrate inferior to the macula with active edges. On SD-OCT, areas of disease activity presented as a diffuse hyperreflective signal in the outer nuclear layer (ONL). Inactive lesions presented as localized thinning of the ONL. NIR allowed clear visualization of a hyperreflective junctional line between the active and inactive areas that subsequently became disrupted. FAF revealed a diffuse hypoautofluorescent halo surrounding an area of hyperautofluorescence in the acute phase and later better-defined lesions and hypoautofluorescent lesion edges.
