Laboratory Evaluation of Thrombophilic Factor in Retinal Vein Occlusive Disease

ABSTRACT

PURPOSE: To evaluate the significance of thrombophilic factors in retinal vein occlusive diseases. METHODS: Thirty-two patients with retinal vein occlusion (19 patients at the age of 55 or less, 13 patients at the age of 56 or more) underwent laboratory evaluation for CBC, lipid profile, VDRL/TPHA, homocysteine, protein C activity, protein S activity, lipoprotein (a), platelet aggregation test, Factor V Leiden, lupus anticoagulant, anticardiolipin antibody, fibrinogen, and antithrombin III. RESULTS: The abnormal laboratory findings (high homocysteine, hyperlipidemia, thrombocytosis, lipoprotein (a), high ESR, and decreased protein S activity) were found more often in patients of 55 years or less than those of 56 or more. CONCLUSIONS: The thrombophilic factors were more common positive findings at or less than 55 years. Thrombophilic factor tests are recommended in young patients with retinal vein occlusion.
