How do you interpret a Fundus Fluorescein Angiography (FFA)? There exist various pinpoint areas of leakage at the level of the retinal pigment epithelium. Fundus fluorescein angiography (FFA) It is a test performed to identify the pattern of blood flow in the two layers of the back portion of the eye namely retina and choroid. Fundus fluorescein angiography was used as an important diagnostic tool to show exact location and extent of vascular changes of PPDR. This gives us more information about the blood supply to suspicious areas at the back of the eye. Es ist ausgesprochen wichtig auszumachen, wie glücklich andere Leute damit sind. Some specifically equipped scanning laser ophthalmoscopes and fundus cameras can use the fluorescence of lipofuscin to document the health of the RPE layer. Leaking fluorescein can come from incompetent blood vessels such as with choroidal neovascularization or retinal neovascularization or through a diseased retinal pigment epithelium that no longer blocks leakage of fluorescein from the choroid. Die Aussagekraft des Vergleihs ist besonders wichtig. The condition has a genetic basis due to mutations in the ABCA4 gene, and results from the accumulation of visual cycle kinetics-derived byproducts in the retinal pigmented epithelium (RPE) with secondary photoreceptor dysfunction and death. Schatz H, Burton TC, Yanuzzi LA, Rabb MF. Greenberg F, Lewis RA. FA has contributed to our understanding of many pathologic processes in the retina and remains the preferred method to image the choroidal and retinal circulation. Researchers show how combined examinations of the posterior pole and nasal mid-peripheral retina can expose retinal lesions in patients with diabetic retinopathy.
