Abstract
Although the importance of the choroidal circulation to maintenance of the sensory retina has long been recognized, little is known of its role in the etiology of retinal and choroidal diseases. In larger part, this is due to fact that vessels of the choroid are obscured by the retinal pigment epithelium, macular xanthrophyll, and choroidal pigment. These pigments, which impede transmission of light in the visible spectrum, inhibit visualization of the choroidal vessels through the pupil with an ophthalmoscope or by visible light angiography. It was not until the development of infrared angiography using indocyanine green (ICG) dye that the routine visualization of in vivo choroidal blood flow was made feasible.
