[Ultrasound examination methods in diagnostics of ischemic lesions of the eye].

One hundred and thirty-eight patients, aged 35 to 70, with acute ischemic neuroopticopathy (54 patients), occlusion of the central retinal artery (CRA--40 patients), chronic neuroopticopathy (21 patients) and chronic ischemic retinopathy (23 patients) underwent ultrasound examinations of the orbital artery (OA), CRA and internal carotid artery (ICA). A more pronouncedly impaired blood flow was registered in OA and CRA in cases of acute clinical forms of ischemic ocular lesions, i.e. a lack of blood circulation in CRA or a significantly diminished blood flow in it; a 2-fold decrease of the maximum systolic blood velocity; a 5-fold decrease of the terminal diastolic blood-flow velocity; and a 1.5 fold increase of the resistance index versus the normal value. Duplex scanning of the carotid arteries enables a timely diagnosis of a hemodynamically valuable ICA stenosis in different clinical forms of ischemic lesions of the eye.
