Indications for<unk>  include: * Choroidal neovascularisation (CNV):Indocyanine<unk>  angiography is widely used to study choroidal neovascularization in patients with exudative age-related macular degeneration. In<unk> , CNV is seen as hyperflourescent spot or plaque. It is also useful in diagnosing and classifying CNV associated to serous pigment epithelial detachments in Nonexudative macular degeneration. * Idiopathic polypoidal choroidal vasculopathy (IPCV) * Pigmented choroidal melanomas * Choroidal haemangioma:<unk>  can be used to differentiate choroidal haemangioma from other intraocular tumors. * Choroiditis: In multifocal choroiditis, lesions are visualized as hypoflourescent spots. * Chorioretinopathy: In Central serous chorioretinopathy, using<unk>  multifocal areas of choroidal hyperpermiability can be visualized. In birdshoot chorioretinopathy, lesions appear as symmetrical round or oval hypoflourescent spots.<unk>  allows better visualization of lesions in serpiginous chorioretinopathy, punctate inner chorioretinopathy, acute zonal occult outer retinopathy etc. In multiple evanescent white dot syndrome, numerous hypoflourescent spots can be visualized using<unk> . * Pigmented epithelial detachment * Retinal angiomatous proliferation (RAP) * Chorioretinal atrophy:<unk>  help evaluating different stages of chorioretinal atrophy. * Anterior uveitis:<unk>  is rarely indicated in anterior uveitis, but it might be used to find out associated choroidal pathology. * Stargardt disease: Numerous hypoflourescent spots are seen in<unk> . * Angioid streaks:<unk>  can be used for diagnosing angioid streaks and their associated ocular pathologies. * Vogt–Koyanagi–Harada disease (VKH):<unk>  is useful in diagnosing VKH. In VKH, delay in filling of the choriocapillaris along with larger choroidal vessel perfusion and multiple hypofluorescent spots are visible with<unk> . * Sympathetic ophthalmia: Sympathetic ophthalmia is a bilateral, granulomatous form of uveitis. In sympathetic ophthalmia, numerous dark spots may be visible during the intermediate phase of<unk> .
