Resumen:

Retinal fluorescein angiography (FA) constitutes a valuable study in the diagnosis and follow-up of patients with inflammatory eye diseases.1 Changes in fluorescence secondary to inflammation are divided into those that produce a hyperfluorescent image and those that produce hypofluorescence (Table 6.1).2 Hyperfluorescence may be secondary to abnormal blood vessels, dye filtration or to a defect in the retinal pigment epithelium (RPE), allowing the choroidal circulation to become more apparent. Hypofluorescence is due to a block in fluorescence (i.e., pigment accumulation) or to a defect in vascular filling.2 © 2009 Springer New York.
