Hyperfluorescent plaque lesions in the late phases of indocyanine green angiography: a possible contraindication to the laser treatment of drusen.

Purpose: To highlight the possible role of indocyanine green angiography in predicting future exudative changes in eyes that are candidates for drusen laser treatment.

Methods: In a 56-year-old woman, fluorescein and indocyanine green angiography were performed before drusen laser treatment.

Results: The treated eye had a suspicious lesion at baseline indocyanine green angiography and a nonsuspicious fluoroangiographic pattern.

Indocyanine green angiography in angioid streaks.

Purpose: To define the indocyanine green angiographic aspects of angioid streaks, peau d'orange and choroidal new vessels.

Methods: Fifty-seven consecutive patients (112 eyes) with angioid streaks were evaluated by fluorescein angiography and indocyanine green angiography.

Results: Indocyanine green angiography showed angioid streaks in all eyes.

Laser photocoagulation of choroidal neovascularization in angioid streaks.

Purpose: To determine if laser photocoagulation of macular choroidal neovascularization in angioid streaks may be effective in preventing severe loss of vision.

Methods: Sixty-six consecutive eyes of 52 patients with extrafoveal, well-defined choroidal neovascularization secondary to angioid streaks who underwent direct laser photocoagulation were followed for 3-108 months (mean, 34.5 months; median, 20 months).

Indocyanine green and fluorescein angiography of surgically excised macular choroidal neovascularizations: correlations with histopathologic and ultrastructural findings.

Background: Informations are expected from the histopathological study of surgically excised choroidal neovascular membranes (CNMs), particularly in relation to the angiographic aspects of vascular architecture.

Methods: Fluorescein and indocyanine green (ICG) angiograms were studied together with the histopathological features of 12 surgically excised subfoveal CNMs in eyes affected by age-related macular degeneration (ARMD).

Results: Instead of the early and delayed diffuse hyperfluorescence secondary to CNMs observed on fluorescein angiography (seven were well defined, five scar evolved), ICG revealed (a) very early hypofluorescence of the membrane bulk over the fluorescence of the outer choroidal vascular bed and (b) late hyperfluorescence gradually increasing and partially defining the border of membranes.

Indocyanine green angiography (ICGA) in pathological myopia.

One hundred and fifty patients (300 eyes), mean age 49 +/- 15 years, with degenerative myopia underwent fluorescein and indocyanine green angiography (ICGA). Fluorescence of choroidal neovascularization (CNV) on ICGA was less evident than with fluorescein angiography (FA). FA revealed CNV in 98 eyes; ICGA showed CNV with different angiographic patterns in 82 eyes.
