title: [Birdshot retinochoroidopathy. Case report].
abstract: The clinical findings and results of perfusion-pressure videoangiography (PVA) are described in a 50-year old patient suffering from birdshot retinochoroidopathy. PVA according to Ulrich and Ulrich makes it possible to observe the gradual filling of the retinal and choroidal vessels relative to ocular perfusion pressure. The patient's PVA reveals that the fluorescein penetrates the vessel wall in the interstitial tissue in the region of the large choroidal arterioles close to the entry of the short posterior ciliary arteries in the eye. This occurs long before the blood flow has reached the choriocapillaries, i.e., at distinctly lower perfusion pressures than are necessary for filling the leaking choroidal capillaries. The leakage of fluoresceine from the large choroidal arterioles explains the typical birdshot pattern of the fundus.
