EYE DISEASES : THE HYPERTENSIVE ANGIOPATHY, RETINAL (ANGIOPATHIA HYPERTONICA RETINAE) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
Etiology. Hypertensive heart disease, vascular sclerosis senile or syphilitic etiology.
The pathogenesis. Allergic changes in retinal blood vessels of the nature of endo - and periarteritis and phlebitis, sometimes leading to obliteration of the vessel or the violation of the integrity of its walls with the formation of extravasation.
Symptoms. In the initial stages of any complaints later complaints about the appearance of dark spots before the eyes, blurred vision. Ophthalmoscopically noted the narrowness of the retinal arteries, tortuosity, storeroot, characterized by the interruption of the column of blood in a vein at the point of inflection through the artery (symptoms chiasm), the white stripes along the arteries; in more advanced cases the entire vessel is drawn in white Tajik and post blood becomes invisible (symptom silver wire); often extravasate.
For chronic; without carrying out the necessary measures against hypertension steadily progressing with the transition in hypertensive retinopathy (see).
Recognition quite easily on the basis ophthalmoscopically picture. The presence of characteristic symptoms helps to distinguish retinal angiopathy from thrombosis of the Central retinal vein (see), the absence of choroidal lesions - hemorrhagic forms of tubercle choroiditis (see Chorionic tuberculosis).
Locally, in the event of a downgrade of view as a result of hemorrhage, - biodegradable agent - iodine-iontophoresis. eye, drops of dionin in increasing concentration from 2 to 6, inside the iodine preparations. Especially recommended osmotherapy (injection of hypertonic solution of sodium chloride or glucose).
