Abstract

Indocyanine green dye angiography has made possible visualization of choroidal blood flow in the human eye; however, to date, its clinical utility has been limited. The complex, multilayered, vascular structure of the choroid and an overlying layer of densely pigmented tissue combine to produce angiographic images of low contrast that are difficult to interpret. Conventional image processing can enhance individual images of the blood vessels, but such an approach contributes no information about the dynamics of blood flow through them. In this paper, an image-processing approach will be discussed that focuses on the dynamic information present in an angiographic sequence. Related topics such as high-speed digital acquisition and low-light-level ophthalmic imaging will also be discussed.
