A small cannula is placed in the vein of the arm. Retinal disease in Susac’s syndrome characteristically manifests as capillary wall hyperfluorescence and arterial occlusion, usually undetectable on funduscopy. Autofluorescence Imaging(FAF) is the concept of using naturally occurring fluorescence from the retina to provide an indicator of RPE (layer of the retina) health.

FFA Retinal vascular layers imaged by fluorescein angiography and optical coherence tomography angiography. Due to the sodium fluorescein molecule's high degree of fluorescence and the minimal penetrability of the background melanin pigment within the retinal pigment epithelium (RPE), fluorescein dye proved to be ideal for studying retinal circulation and retinal vasculature. Methods This post-hoc analysis of a randomised controlled trial included a total of 54 patients with active mCNV. Fluorescein angiography is a diagnostic technique that allows the sequential visualization of blood flow simultaneously through retinal, choroidal, and iris tissues as the fluorescein dye is injected into the bloodstream via the vein in the arm.

Complete blood cell count with differential. methods include sodium fluorescein angiography (abbreviated FA or FAG) and indocyanine green (abbreviated ICG) angiography. After taking a few pictures of the fundus (back of the eye), an orange-yellow coloured fluorescein dye is injected through the cannula. Purpose To evaluate the utility of widefield optical coherence tomography angiography (WF-OCTA) compared with clinical examination in grading diabetic retinopathy in patients diagnosed clinically with proliferative diabetic retinopathy (PDR) or severe non-proliferative diabetic retinopathy (NPDR). METHODS 307 cases (from 212 patients) of fundus fluorescein angiograms performed in patients with myopic degeneration were evaluated to find the circle of Zinn–Haller and to observe its fundus fluorescein angiographic features. It typically involves a table top setup with a non portable fundus camera. Leakage refers to the gradual, marked increase in fluorescence throughout the angiogram when fluorescein molecules seep through the pigment epithelium into the subretinal space or neurosensory retina, out of retinal blood vessels into the retinal interstitium, or from retinal neovascularization into the vitreous. Originally, VKH disease was classified as two separate entities:Since there is much overlapping of signs and symptoms between the two entities, in 1932 Babel suggested to call the entity Vogt-Koyanagi-Harada disease.

Additional … The chemical called fluorescein temporarily lights up the blood vessels. Purpose The present study aimed to evaluate the characteristics of fundus autofluorescence in Japanese patients with retinal angiomatous proliferation (RAP). However, it can be useful at initial presentation whenever fundus changes are not obvious. For nearly 50 years, fundus photography and fluorescein angiography have been valuable in expanding our knowledge of the anatomy, pathology, and pathophysiology of the retina and choroid.
