Indocyanine green angiography is a diagnostic study where indocyanine green, a fluorescent dye, is injected intravenously, and observations of the retina are made at intervals as increasing intensity of retinal and choroidal circulation is displayed.- MDA
WAILEA, Hawaii – Indocyanine green angiography as an ancillary retina test is relevant in 2015 as a limited part of multimodal imaging, a presenter said.
As an ancillary test, indocyanine green (ICG) angiography has better absorption through pigment and blood, it is highly protein bound, which equates to less leakage from the choriocapillaris, and it avoids the allergy concerns of fluorescein. The two major conditions that ICG angiography is used to diagnose are polypoidal choroidal vasculopathy and central serous chorioretinopathy, he said.
Disadvantages of ICG angiography are that it is not widely available, it is expensive, it is contraindicated in shellfish allergies, it has no utility in dry AMD and minimal benefit in wet AMD treated with anti-VEGF monotherapy, and there is no benefit in other retinal vascular disorders, such as diabetic retinopathy and retinal vein obstruction, according to the presentation…….
