Atherosclerosis affecting vision: therapy.

Abstract

The visual consequences and the pathogenesis and therapy of atherosclerosis are discussed. Atherosclerosis apparently is the result of hepatic failure to produce a stable suspension of cholesterol esters in the plasma. In some instances this represents an inherent metabolic defect. Usually it represents improper diet, namely, the excessive intake of saturated fatty acids and the inadequate intake of polyunsaturated fatty acids. Excessive ingestion of carbohydrates, insufficient physical exercise and reduced thyroid function are contributing causes. The final common denominators leading to tissue injury and destruction are vascular insufficiency and hypoxia. Hypertension is a separate disease, often concurrent with atherosclerosis. In diabetes, also a separate disease, atherosclerosis is one of the sequelae. Therapy primarily consists of the reduction or elimination of meat and milk fats from the diet, and the inclusion or increase of marine fats and vegetable oils. Simultaneously, carbohydrate intake is restricted. Adequate thyroid function, a normal hemoglobin level, and sufficient physical exercise are important. A supplementary intake of vitamins B6 and E, and of lipotropic substances is recommended.
