Indocyanine green angiographic feature in poterior cleriti

PURPOE: To determine choroidal involvement in poterior cleriti by examining indocyanine green angiographic feature. METHOD: Indocyanine green angiography wa performed according to a tandard uveiti angiographic protocol in eight conecutive patient with poterior cleriti. Indocyanine green angiography data were compared to fundu color photograph, red-free photograph, and fluorecein angiography. REULT: The principal indocyanine green angiographic feature wa diffue zonal choroidal indocyanine green hyperfluorecence in the intermediate (±10 minute) and late (±40 minute) phae of angiography preent in all eight patient who regreed in repone to anti-inflammatory therapy. In four patient (two with maive ubretinal exudation), additional fluorecing pinpoint were preent in the zonal hyperfluorecent area. Additional feature included irregular delayed choroidal perfuion (five of eight patient)—irregularly ditributed dark dot that were preent up to the intermediate phae and becoming iofluorecent in the late phae that gave a mottled apect to the choroid—and enlargement of draining choroidal vein. In bilateral patient, clinical feature and indocyanine green angiography ign were roughly ymmetric. CONCLUION: In poterior cleriti, indocyanine green angiography allowed u to identify area of choroidal hyperfluorecence, poibly indicating area of maximal inflammatory activity, and demontrated regreion of hyperfluorecence in repone to therapy. Indocyanine green angiography wa ueful in aeing the extent of choroidal involvement and will probably erve a one of the follow-up parameter for dieae evolution and repone to therapy.
