Impaired Choroidal Blood Flow in Adolescents with Essential Arterial Hypertension

Arterial hypertension is a problem not only for adults, but also for children, but there are very few data on changes in the organ of vision under the influence of an elevated level of blood pressure in children.The aim of the work is to identify disturbances of the choroidal blood flow in children...
