Fluorangiography

Fluorescein angiography, also called angiofluoresceinography, is a diagnostic technique used in medicine to study the blood vessels of the retina. The retina is the layer of light-sensitive tissue inside the eye, thanks to which vision is possible.

It consists of the intravenous administration of a coloring substance called fluorescein. This dye circulates through the bloodstream and reaches the vessels of the retina, where it emits a characteristic phosphorescence that can be captured by special cameras. The images thus obtained are printed on paper and allow the retinal blood vessels to be observed and check for abnormalities, such as hemorrhages, thrombosis or embolisms.

This technique can be used by the ophthalmologist for the diagnosis and evaluation of multiple diseases, such as diabetic retinopathy, age-related macular degeneration, retinal detachment, retinitis pigmentosa or occlusion of the retinal vessels as occurs in embolism of the central retinal artery and in central retinal vein thrombosis.
