Indocyanine green angiography (ICGA) is preferred over fluorescein angiography for evaluating which of the following conditions?

• A Diabetic macular ischemia
• B Cystoid macular edema
• C Retinal vein occlusion
• D Polypoidal choroidal vasculopathy ✓

Explanation

ICGA uses a larger protein-bound molecule that does not leak from the choroidal circulation, and its near-infrared wavelength penetrates hemorrhage and pigment, making it ideal for visualizing choroidal polyps and branching vascular networks in polypoidal choroidal vasculopathy. FFA is superior for retinal vascular pathology like diabetic ischemia, vein occlusion, and cystoid macular edema.
