A diagnosis is made by a clinical examination with a slit lamp and by using several types of imaging
FLUORESCEIN ANGIOGRAPHY (FA)
An imaging technique where a yellow dye called sodium fluorescein is injected into a vein in the arm, allowing a special camera to record circulation in the retina and choroid in the back of the eye. This test can be very useful in diagnosing a number of retinal disorders.
INDOCYANINE GREEN ANGIOGRAPHY (ICGA)
A diagnostic procedure that uses a green dye to illuminate blood flow in the choroid, which is a layer of blood vessels located between the white of the eye (sclera) and the retina that supplies nutrients to the inner eye.
OPTICAL COHERENCE TOMOGRAPHY (OCT)
A non-invasive imaging technique that uses light to create a 3-dimensional image of your eye for physician evaluation.
