A unique characteristic of the ocular circulation is that it is availableto direct, noninvasive evaluation, offering a window to study structural andfunctional changes in the human circulation in diseases affecting not onlythe eye (eg, age-related maculopathy) but also elsewhere in the body (eg,hypertension).
