Two medical students from Indiana University, Harold R. Novotny and David L. Alvis, described and demonstrated the technique of retinal fluorescein angiography (FA) in 1961. Differences between the two dyes are shown in Table 4-1.Sodium fluorescein is a highly water-soluble yellow-red dye with peak absorption in the blue spectrum (490 nm) and emission in the yellow-green spectrum (525 nm) ().This difference in excitation and emission spectra permits coupled photographic filters to separate incoming and exiting light. Normal : Non-tapetal fundus • non-tapetal fundus • (optic disc) • (retinal blood vessels) RPE contains melanin, where the tapetum is absent. Fluorescein angiography records the dynamic interaction of fluorescein with both normal and abnormal anatomic structures of the ocular fundus. Film based autofluoresence of optic disc drusen. Illuminating the retina with blue light causes certain cellular components to "glow" without injecting any dye. Fundus autofluorescence (FAF) is a relatively new, non-invasive imaging modality that has been developed over the past decade. Since the technique was first described, less than 20 years ago, a tremendous amount of angiographic data has been accumulated, which has had a revolutionary impact on the understanding of fundus disease.
