[Evaluation of the general condition and selected biochemical blood parameters in various types of retinal vein...

The aim of the study was to evaluate the coagulant and fibrinolytic system, lipid economy and neurological condition in patients with various types of retinal vein occlusion. The material was 70 patients: 8 with diagnosed congestive venous retinopathy, 27 with ischaemic central retinal vein occlusion and 35 with central retinal vein branch occlusion. Apart from the neurological evaluation, every patient underwent determination of: hematocrit, number of blood platelets, total plasma protein with its electrophoretic division, plasma fibrinogen level, kaolin-cephalin and prothrombin coefficient, and the level of triglycerides, total cholesterol with its fractions LDL and HDL.

Considerable percentage of patients with arterial hypertension and suffering from partial or multi-symptomatic hemiparesis associated with complication in plasma lipid content indicates significant atheromatous changes in vascular wall which promote occlusion formation. The role of rheological factors in pathogenesis of these changes seems to be secondary.
