    Abstract:
    BACKGROUND: Inflammatory choriocapillaropathies (choriocapillaritis) correspond to the clinical spectrum of lesions of the fundus, including acute posterior multifocal placoid pigment epitheliopathy (APMPPE), multiple evanescent white dot syndrome (MEWDS), multifocal choroiditis (MC), and other rarer entities caused by inflammatory disturbances of choriocapillaris perfusion. The aim here was to study the sensitivity of indocyanine green (ICG) angiography in investigating and following inflammatory choriocapillaropathies. PATIENTS AND METHODS: Patients with inflammatory choriocapillaropthies were included who had had a dual fluorescein and ICG angiography as well as visual field testing (Goldman or computerized perimetry) at presentation and on follow-up visits. ICG angiography was performed according to a routine angiographic protocol used for inflammatory diseases and was correlated with fundus examination, fluorescein angiography, and visual field testing. RESULTS: Three patients with MEWDS, two with APMPPE, and two with MC were included. The visual field alterations in all seven patients were well correlated with the extent of the hypofluorescent areas seen on ICG angiography, whereas they were badly correlated with fluorescein angiographic signs and their evolution. The visual field in MEWDS was particularly well correlated with the importance of peripapillary hypofluorescence seen on ICG angiography. In MC, the evolution of new lesions was well demonstrated by ICG angiography and well correlated with visual symptoms and visual fields, but was barely detected on fundus examination and by fluorescein angiography. CONCLUSIONS: ICG angiographic signs were shown to be closely correlated with visual function (visual field testing). This was not the case for either fundus examination or fluorescein angiography. ICG angiography appears as a very sensitive follow-up parameter in inflammatory choriocapillaropathies, giving morphological information on the evolution of the disease and on the response to treatment when therapy is indicated.
