fluoresceinangiografia

Fluorescein angiography is a medical imaging technique used to visualize the blood vessels in the retina and other parts of the eye. It is a diagnostic tool that helps doctors diagnose and monitor various eye conditions, particularly those affecting the blood vessels in the eye.

The procedure involves injecting a fluorescent dye, usually fluorescein, into the vein. The dye is then illuminated with a blue light, which causes it to fluoresce. This is captured by a specialized camera, producing a series of images that show the blood vessels in the eye. The images are then reviewed by a doctor to identify any abnormalities, such as leaks or blockages, in the blood vessels.

Fluorescein angiography is commonly used to diagnose and manage conditions such as diabetic retinopathy, macular degeneration, and retinal vein occlusion. It can also be used to evaluate the effectiveness of treatments, such as laser therapy, for these conditions. In addition, fluorescein angiography can help identify other eye conditions, such as choroidal neovascularization and retinal detachment.

The procedure is usually painless and takes about 30 minutes to an hour to complete. The patient is seated comfortably in a chair, and the camera is positioned to capture the images of the eye. The images are then reviewed while the patient is still in the chair. Fluorescein angiography is a safe and effective diagnostic tool, and it is widely used in ophthalmology to help doctors diagnose and manage a range of eye conditions.
