WHAT IS FLORESCEIN ANGIOGRAPHY ?
Florescein Angiography (FA) allows study of the circulation of the retina and choroid in normal as well as diseased states. It is a diagnostic procedure in which an intravenous injection of sodium fluorescein is administered after which photographs of retina are taken.
Commonly known as fluorescein dye, sodium fluorescein is used to highlight the blood vessels in the back of the eye so that they can be photograph in order to arrive at a diagnosis/prognosis based on patient’s condition. A special camera is used to record the blood flow in the retina.
The test doesn’t involve any direct contact with the eyes. The patient’s eyes are dilated before the procedure.
The procedure takes about 30 minutes. The doctor can generally review the results soon after.
Florescein Angiography is a valuable test that provides vital information about the retina. The dye that gets injected appears in the blood vessels on retina in 10-15 seconds on average. As the dye travels through the retinal blood vessels, an ophthalmic photographer shoots pictures of retina with a retinal camera. In case of any abnormalities of the retina, the dye usually leaks or reveals by staining or by means of its inability to get through any blocked blood vessels.
Some of the common eye conditions that are commonly diagnosed with florescein angiography are – Diabetic Retinopathy, Central Serous Retinopathy and Macular Degeneration.
