The Ocular Blood Flow Service

Located at Long Island College Hospital, the Ocular Blood Flow Service evaluates blood flow to the optic nerve, retina and choroid utilizing the Heidelberg Retinal Tomography/Flowmeter, and the Heidelberg Fluorescein Angiography/ Indocyanine Green instruments.

The Indiana Technique

Ocular blood flow analysis at the University Ophthalmic Consultants (UOC) is performed in a unique, collaborative effort with Indiana University -- arguably the most sophisticated blood flow analysis laboratory in the world. Our results have been demonstrated to surpass those of commercial laboratories. The Indiana technique uses a customized analysis, pixel by pixel, of the retina capillary and choroidal blood flow. This allows us to identify progressive blood flow abnormalities that cannot be detected by other techniques.

Blood flow analysis may lead to more appropriate medical treatments than might otherwise be administered. Patients who experience optic nerve damage despite "normal" pressures can have their blood flow analyzed before and after medication to determine the most effective treatment for them.

The sensitive instruments used by the UOC Ocular Blood Flow Service are used mostly in research, but it is of increasing value in clinical cases as well. They provide a powerful tool for evaluation of blood flow in people with diabetes, age-related macular edema, glaucoma, and decreased blood supply to the eye.
