Abstract:
The retinal and choroidal blood vessels respond independently to the abruptly increased arterial pressure due to their differences in the anatomic and physiologic properties, which induce hypertensive retinopathy and hypertensive choroidopathy respectively. The authors reviewed the fluorescein angiogram retrospectively to observe the ischemic changes of the choroid in 15 cases of hypertensive choroidopathy. The ischemic changes of the choroid in hypertensive choroidopathy were characterized by generalized or sectorial filling delay which was followed by staining or leakage of dye. These findings suggest that the choroidal circulation may lead to the sectorial and generalized ischemic conditions following the abruptly increased arterial pressure due to their differences in the anatomic structures. The fluorescein angiographic findings in the hypertensive choroidopathy depend on both the degree of the circulatory disturbance and the levels of the affected choroidal vessels.
