BACKGROUND: The present study investigates how often a simultaneous fluorescein and indocyanine green (ICG) angiography had therapeutic consequences and if it is useful as a clinical routine diagnostic tool. PATIENTS AND METHODS: 502 consecutive simultaneous angiographies in eyes with exudative macular degeneration were retrospectively studied. RESULTS: A classic extra- or juxtafoveolar choroidal neovascularisation (CNV) was found in 3.5 % of the eyes. A subfoveal predominantly classic CNV was present in 19 % of the angiographies. ICG angiography showed a vascular network in 3 % of the eyes with occult CNV in fluorescein angiography. A neovascularisation supplied by retinal vessels (retinal angiomatous proliferation) was found in 9 % and a polypoidal choroidal vasculopathy (PCV) in 6 %. Other plaques or hot spots were visible in 4 %. In 11 eyes with progressive exudation from PCV and threatening of the fovea, laser treatment was successfully performed. CONCLUSIONS: Combined angiography identifies treatable PCV. Advantages of a combined procedure (easier logistics, no missing of treatable cases) and arguments for a two step procedure with ICG angiography only in selected cases (lower costs, lower rate of adverse reactions) must be weighed against each other.
