title: [Acute insufficiency of the ophthalmic artery during occlusion of the internal carotid artery].
abstract: The authors present a case of a patients aged 41 years in whom the acute insufficiency of the ophthalmic artery was the first and single sign of an internal carotid occlusion. Doppler's pulsating focused ultrasonography showed to be an indispensable method which rendered possible a prompt diagnosis. Besides--this methods enables us to evaluate the dynamics of changes--the regeneration of the ciliary circulation with a compensatory perfusion of blood in some branches of the posterior ciliary arteries, the creation of collateral circulation from the ipsilateral external carotid artery through the ophthalmic artery with a reverse direction of perfusion in its extent and creation of a collateral circulation from the contralateral internal carotid through the anterior cerebral artery.
