Fluorescensangiografia
Fluorescein angiography is a medical imaging technique used to examine blood flow in the retina and choroid, the vascular layers of the eye. It involves injecting a fluorescent dye, typically fluorescein sodium, into a vein in the arm. As the dye circulates through the bloodstream, it reaches the blood vessels in the eye. A specialized camera with a blue light source and filters is then used to capture a series of rapid photographs or a video of the eye's interior. The fluorescein dye absorbs the blue light and then emits a yellowish-green light, making the blood vessels clearly visible.
This diagnostic tool is crucial for detecting and monitoring a variety of eye conditions. It helps identify
