![]() Indocyanine Green Angiography, or ICG, is much like fluorescein angiography with the addition of a green cyanine dye. Fluorescein angiography usually takes about fifteen to twenty minutes. If undergoing fluorescein angiography patients are urged to alert their physician and photographer of any know allergies to iodine, shellfish or contrast dyes. The fluorescein sodium dye may give a yellowish tint to the patient’s skin and it usually turns urine a bright yellow or orange color for 24 to 36 hours. Although complications and side effects are rare with fluorescein sodium they include inflammation, pain or bruising at the injection site and more rarely, itching, hives, breathing difficulties or even more severe allergic reactions. Leakage, blockage and other vascular abnormalities may be disclosed which can aid in the diagnosis and evaluation of many retinal conditions. Within seconds, a series of photographs or video is taken to document the circulation of the dye through the arteries and veins in the retina. Fluorescein sodium, a diagnostic dye, is injected through a small butterfly needle into a vein in the arm. Fluorescein Angiographyįluorescein angiography is an imaging technique that highlights the circulation of the retina using a series of rapid-sequence photographs or video imaging. Fundus photography usually takes about five to ten minutes. These photographs are commonly combined with fluorescein angiography to further evaluate retinal conditions. ![]() This non-invasive procedure allows the retinal specialist to document retinal structures or pathology which can be used for future comparison. The term fundus describes the back of the eye including the retina and the optic nerve. Fundus Photographyĭigital color photographs are taken of the retina using specialized fundus cameras. The retinal thickness is also measured which can aid in the diagnosis and monitoring of many retinal diseases. As it scans the macula, a detailed and magnified cross sectional image is produced which is used to document retinal structures and pathology. Optical Coherence Tomography, or OCT, is a non-invasive, fast-imaging, scanning technology that utilizes coherent light beams to document retinal structures or pathology.
