ABSTRACT

Retinitis pigmentosa is the most common retinal dystrophy; the vascular changes are related to its pathophysiology, although the damage or circulatory disorders are not its primary cause. A descriptive and cross-sectional study was conducted in the National Reference Center of Retinitis Pigmentosa, in Havana, in order to identify the situation of the peripheral circulation in patients with retinitis pigmentosa by means of a carotid Doppler. From a total of 400 patients suffering from this condition a sample of 158 patients was selected, after applying the inclusion and exclusion criteria. The variables age, sex and stage of the disease were analyzed; the latter according to the classification of the Cuban School of Retinitis pigmentosa. All patients underwent a carotid Doppler. The results were considered as negative ones (in the absence of atherosclerotic plaques and turbulence and permeable vertebrobasilar system) and pathological ones (atheromatous plaques, turbulent flow and stenosis of the vessel lumen examined or their branches). The data were processed by descriptive methods (percentages). The age range more commonly presented was between 41 and 50 years of age (32.91%), females predominated (60.12%) and normal Doppler (68.35%). The highest percentage of peripheral circulatory disturbances (32.0) occurred in patients in stage IV of the disease. Alterations of the peripheral circulation shown in carotid Doppler examination of patients were mainly those from the last stage of evolution of the disease.
