Home » Our Services » Fundus Fluorescein Angiography (FFA) Fundus Fluorescein Angiography (FFA) This test involves injecting dye into the bloodstream and taking a picture of it as it runs through the eyes. Type I PED well-defined area of early hyperF, Type II late leak of undeyermined source not, Fluorescein Angiography, technique interpretation. The dye is metabolized by both hepatic and renal pathways and is excreted in the urine within 24-36 hours. The time it takes for the dye to reach the eye via this pathway is known as transit time. Old Females Males White ... 1871 Baeryer combined resorcinal phthalic acid, 1882 Ehrlich introduced fluorescein into, 1940 Gifford studied aqueous dynamics after, 80 albumin bound 20 left for fluorescence, Rapid diffusion through intra extracellular, Diffuses freely through choriocapillaris, Bruchs, Stains skin mucous membranes yellow for 24, Metabolised by liver excreted via kidneys, Absorbs light in blue range (490nm) emits in. No Normal eyelid closure? As the dye passes through your retina, a special camera takes pictures. The dye travels to your eye where it highlights the blood vessels. The dye sodium fluorescein can be used either in concentration of 10% or 20% in the form of intravenous bolus injection.It is used to image retinal, choroidal, optic disc, or iris vasculature, or a combination of these. | PowerPoint PPT presentation | free to view Boasting an impressive range of designs, they will support your presentations with inspiring background photos or videos that support your themes, set the right mood, enhance your credibility and inspire your audiences.

There are many diseases can impair damage or permanently affect vision in children. Instil the dye by either touching a fluorescein strip to the inside of the lower eyelid, or applying a drop of fluorescein dye eye drops; ask the patient to blink to distribute the dye. - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. Fluorescein flows from the injection site to the heart and then, is pushed into the systemic vascular tree. - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. presentations for free. - Can show thickening or pneumatosis intestinalis ...
