In all patients complete ophthalmology examination was performed and we measured lipid profile, glucose, alanine aminotransferase \(AlAT\), creatinine, total homocysteine, Creactive protein \(CRP\), fibrinogen, tissue plasminogen activator antigen \(tPA\), plasminogen activator inhibitor\-1antigen \(PAI\-1\), activated partial thromboplastin time \(APTT\), and prothrombin time \(PT\). In RVO patients thrombophilia screening was done. Moreover, ex vivo fibrin clots obtained from citrate plasma samples were used for the measurement of clot permeation, expressed as the permeability coefficient, Ks \(Darcy constant\). Turbidity offibrin clot formation, reflected by the lag phase of theturbidity curve and maximum absorbency at plateau\(ΔAbmax\), tPA – induced fibrinolysis characterized bymaximum rates of increase in D\-dimer levels \(D\-Drate\) andmaximum D\-dimer concentrations \(D\-Dmax\) wereevaluated. The time required for 50% decrease in maximumclot absorbency \(t50%\) was chosen as an additional markerof the clot susceptibility to fibrinolysis after simultaneous addition of thrombin and recombinant tPA to plasma. \; Both RVO and control groups did not differ with regard toage,"]
