Popis: Background: Retinal vein occlusion is the most common retinal vascular disorder after diabetic retinopathy with several ocular and systemic disorders associated with retinal veins thrombosis. Factor V Leiden (FVL) mutation as part of inherited thrombophilia may associated with retinal vein thrombosis. Objectives: Determine the presence of FVL mutation in a set of Iraqi patients with retinal vein thrombosis and evaluate its role in the etiology of thrombosis in those patients. Patients, Materials and Methods: A case-control study conducted for 6 months, a total number of 69 patients who were diagnosed with retinal vein thrombosis while attending ophthalmology outpatient clinic in Diwania city in Iraq. Only sixty patients were eligible for the study. From each patient, venous blood was withdrawn for complete blood count, blood film, erythrocyte sedimentation rate, kaolin clotting time, anticardiolipin antibodies, antinuclear antibody, thyroid-stimulating hormone, renal function test, random blood sugar, and serum cholesterol in addition to determine the presence of FVL mutation by polymerase chain reaction (PCR)-restriction fragment length polymorphism. For 84 individuals of control group, only the presence of FVL mutation by PCR was done. Results: Sixty out of 69 patients with retinal vein thrombosis were eligible for the study. There were a total of 34 males and 26 females with a mean age of 49.1 ± 2.03 years with no significant statistical differences in mean age and sex between the patients and the control groups. The proportion of patients with FVL mutation was higher than that of control subjects, 21.7% versus 8.3% (P = 0.023). FVL mutation in patients group showing a significant risk factor to develop retinal vein thrombosis than control group (odd ratio: 3.043). Conclusions: FVL plays a role in etiology of retinal vein thrombosis and measurement of this mutation with proper prophylaxis may be useful in prevention of venous thrombosis.
