Fluorescein angiography [1] (FA), fluorescent angiography (FAG), or fundus fluorescein angiography (FFA) is a technique for examining the circulation of the retina and choroid (parts of the fundus) using a fluorescent dye and a specialized camera.

2024年2月13日 · Fluorescein angiography is a type of eye test used to diagnose retinal conditions. It can also be used as an early way to gauge whether someone might have complications...

2023年8月25日 · Fundus fluorescein angiography (FFA) is an invasive diagnostic procedure. It helps to assess the anatomy, physiology, and pathology of retinal and choroidal circulation. It aids in the diagnosis of various ocular pathologies. It contributes to decision-making when planning the management of ocular pathology. It is also useful as a teaching tool.

2021年6月28日 · Fluorescein angiography (FA) is when your ophthalmologist uses a special camera to take pictures of your retina that give a better look at the back of the eye.

Know all there is about the Fundus Fluorescein Angiography (FFA), a test performed to diagnose a number of potentially harmful eye diseases. Read up on its indications, preparation, procedure, side-effects, and advantages.

2020年7月1日 · A fluorescein angiography is a medical procedure in which a fluorescent dye is injected into the bloodstream. The dye highlights the blood vessels in the back of the...

2020年7月1日 · Fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) are essential tools in assessing the activity and extent of inflammation in Behçet retinal vasculitis [10]. FFA allows for early recognition of retinal vascular inflammation, vascular occlusion and macular ischemia even before they are clinically evident [11].

Fluorescein angiography is an imaging modality used to investigate the integrity of the choroidal and retinal circulations. Fluorescein dye is injected intravenously and photographs are subsequently taken of the fundus as the fluorescein circulates in the vasculature and tissues of the retina and choroid.

FA requires the use of a dedicated fundus camera equipped with excitation and barrier filters. 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. White light from a flash is passed through a blue excitation filter.

2024年11月26日 · A fluorescein angiogram (FA) or fundus fluorescein angiography (FFA) looks at the blood vessels and the lining at the back of your eye (the retina). You may also have a photograph taken of the surface of the inside of the eye (the fundus). This is called a colour fundus photography.
