Precise monitoring and differentiation of inflammatory events by indocyanine green (ICG) angiography in a case of recurrent posterior sarcoid uveitis

PURPOSE: By providing information on choroidal lesions, indocyanine green (ICG) angiography is complementary to fluorescein angiography in the workup of posterior uveitis. The aim here was to illustrate practically the suitability of performing dual fluorescein/ICG angiograms in a demonstrative case of recurrent presumed posterior sarcoid uveitis. METHODS: Sequential dual fluorescein/ICG angiograms were performed for the workup and follow-up of a case of recurrent presumed sarcoid uveitis. RESULTS: Dual fluorescein and ICG angiograms performed during the first recrudescence of inflammation showed mainly retinal involvement with cystoid macular edema, diffuse posterior pole retinal hyperfluorescence, and papillitis, whereas the second recurrence after tapering oral corticosteroid therapy showed new choroidal lesions of the posterior pole in the absence of significant retinal involvement. CONCLUSIONS: Dual fluorescein/ICG angiography clearly allowed the differentiation of two different inflammatory events, one involving the retina and the other involving the choroid, at the origin of similar clinical manifestations.
