Abstract

PURPOSE:

To evaluate the digital indocyanine green (ICG) videoangiography characteristics of well-defined choroidal neovascularization (CNV).

METHODS:

The authors retrospectively reviewed all ICG angiograms performed at the New England Eye Center over a 2-year period. Included in this study were all patients with the clinical and fluorescein angiographic diagnosis of well-defined CNV according to the Macular Photocoagulation Study Group criteria.

RESULTS:

Of the 25 eligible patients, 18 (72%) had a well-demarcated area of ICG hyperfluorescence that was observed either both early and late (6 patients = 24%) or only late (12 patients = 48%) on the ICG angiogram. Five patients (20%) showed only poorly demarcated late hyperfluorescence on ICG angiography. Two patients (8%) had type II occult CNV associated with classic CNV as per the Macular Photocoagulation Study Group criteria. Both patients showed a late, well-demarcated area of ICG hyperfluorescence greater than the area imaged with fluorescein angiography.

CONCLUSIONS:

Choroidal neovascularization which is well-defined on fluorescein angiography has variable ICG appearances. When there is late leakage associated with a well-defined CNV on fluorescein angiography (type II occult CNV), ICG angiography may more completely delineate the extent of the lesion.
