A delayed image is obtained at 5 and 10 minutes. [1] John Donald McIntyre Gass began publishing his experience with FA in 1967 and his efforts led to the wider acceptance of the technique in the evaluation of retinal disease. After 10 minutes fluorescein is usually no longer seen in retinal vessels however several structures including the optic nerve head, Bruch’s membrane, and sclera are stained with fluorescein and continue to fluoresce. The condition has a genetic basis due to mutations in the ABCA4 gene, and results from the accumulation of visual cycle kinetics-derived byproducts in the retinal pigmented epithelium (RPE) with secondary photoreceptor dysfunction and death. 1990;110:323-5. Visual acuity was 6/5 in the right eye. Fluorescein angiography finds its origins in the late 1960s with the publication of an original article describing its use as well as subsequent atlases and textbooks for a medical retinal specialty in its infancy. More severe reactions such as urticaria, pyrexia, thrombophlebitis, and syncope are more rare. Further, imaging facilities should be adequately equipped and prepared to manage complications associated with fluorescein angiography. 7 In the later phases the localized hyperfluorescent spots increase in size, coalesce, and expand into the subretinal space in areas of serous detachment … We do this commonly when looking at the cornea after instilling fluorescein. Sodium fluorescein is added into the systemic circulation, the retina is illuminated with blue light at a wavelength of 490 nanometers, and an angiogram is obtained by photographing the fluorescent green light that is emitted by the dye.
