Indocyanine green angiographic findings in multifocal choroidopathies.
With high definition videoangiography (TOPCON IMAGEnet H1024) the Authors studied 41 patients affected by multifocal choroidopathies (MC) (68 eyes with ophthalmoscopic or indocyanine green angiographic evidences): 29 females and 12 males; age 21-51 years with a follow up of 6-29 months. In the light of the evidence provided by FA and ICG the Authors present a classification of MC in three stages: Stage 1 of subclinical choroidal activity (5 eyes): characterised by the presence of hypofluorescent or hyperfluorescent spots visible only in the late phases of ICGA; stage 2 of clinically evident choroidal activity (45 eyes): in FA the spots are hypofluorescent in the early phases and hyperfluorescent with a slight diffusion in the late phases, in ICGA either hypofluorescent spots or less frequently hyperfluorescent spots and choroidal permeability alterations can be observed; stage 3 or healed stage (18 eyes): in FA the spots are hyperfluorescent without late leakage, in ICGA hypofluorescence can be observed during all angiographic phases. In 5 patients in stage 1 of subclinical activity, a systemic steroid therapy induced the regression of the hypofluorescent sports in ICGA, in 2 cases the regression of hyperfluorescent spots in ICGA was observed after systemic antibiotic therapy. The authors underline that ICGA could be a particularly useful tool for an early diagnosis and clinical monitoring of MC.
