[Ophthalmocalibrometric assessment of the state of the microcirculation in the retinal vessels in transient disorders of cerebral circulation].

The report analyses some results of a neuro-ophthalmological study of 82 patients from 34--76 years (37 males and 45 females) with transient disorders of cerebral circulation. Besides clinical studies the authors applied EEG and REG registrations, studies of the lipid metabolism, coagulative and anticoagulative blood systems. Ophthalmological studies included the assessment of visual acuity with and without correction, quantitative perimetry, the determination of a genuine intra-ocular pressure, ophthalmodynamometry, biomicroscopy of the conjunctiva and episclera, biomicro-ophthalmoscopy, ophthalmoscopy with the use of electro-ophthalmoscopy, a large nonreflex ophthalmoscope, ophthalmocalibrometry. By means of ophthalmocalibtometrical studies the authors established an existence of expressed pathology of microcirculation in the form of a marked narrowing of arterioles and a dilatation of the venoules with a significant decrease of the arterio-venous correlations. The achieved data are analyzed with consideration of the etiology, development and topography of transient disorders of cerebral circulation.
