[Lipid metabolism disorders in patients with retinal artery occlusions]

Triglycerides, cholesterol, HDL-cholesterol, LDL-cholesterol, the HDL-cholesterol/LDL-cholesterol and cholesterol/HDL-cholesterol ratio, the apolipoproteins A and B, and the ratio apo A/apo B were determined in patients with occlusions of retinal arteries and compared with a control group. The patients showed higher levels of triglycerides, cholesterol, LDL-cholesterol, apo B and the ratio cholesterol/HDL-cholesterol and a decrease in HDL-cholesterol and the two ratios HDL-cholesterol/LDL-cholesterol and apo A/apo B, indicating that disturbances in lipid metabolism may be a risk factor in the development of occlusions of the retinal arteries.
