Sodium fluorescein is added into the systemic circulation, the retina is illuminated with blue light at a wavelength of 490 nanometers, and an angiogramis obtained by photographing the fluorescent green light that is emitted by the dye. The retinal circulation appears 1-3 seconds later (11-18 seconds after injection). In the later phases the localized hyperfluorescent spots increase in size, coalesce, and expand into the subretinal space in areas of serous detachment … It is a very helpful in-vivo mapping of naturally or pathologically occurring fluorophores of the ocular fundus. This most commonly occurs when RPE is missing and the bright choroidal fluorescence is seen early in the FA. The black and white images are filtered red-free (a green filter) to increase contrast and often gives a better image of the fundus than the color image. Pp 148. 1967;78:455-461. The fluorescein is administered intravenously in intravenous fluorescein angiography (IVFA) and orally in oral fluorescein angiography (OFA). Areas of leakage in an FA show gradual enlargement and blurring of their margins. Staining results in increasing fluorescence throughout the angiogram but the margins remain distinct. A filter is placed in the camera so only the fluorescent, yellow-green light (530 nm) is recorded. St. Louis:Mosby-Year Book:1978. ICD 10 Data 1. Fluorescein dye is injected intravenously, usually through an antecubital vein with sufficient speed to produce high contrast images of the early phases of the angiogram. Disease Database 3.
