[Clinical picture of open-angle glaucoma in patients with critical stenosis of the internal carotid artery].

Clinical picture of primary open-angle glaucoma (POAG) was studied in 32 patients (57 eyes) with pronounced stenosis of the extracranial segment of the internal carotid artery (ICA) on the side of the glaucomatous eye. Major clinical signs were detected: conjunctival angiopathy, pronounced diffuse dystrophy of the iris, absence of pigmented iridal rim, pseudoexfoliations, pale optic disk with saucer-like excavation of different severity. Intraocular pressure (IOP) was 26-34 mm Hg and could not be normalized by drug therapy or antiglaucomatous surgery. Ultrasonic methods for examination of the eyeball vessels showed pronounced decrease of the bloodflow velocity and a significant increase of resistance index in the orbital and central retinal arteries. Reconstructive operations on the carotid arteries performed in POAG patients for critical stenosis of ICA improved the eyeball hemoperfusion and decreased IOP.
