    Abstract:
    PURPOSE: The purpose of the examination was evaluation of tissue plasminogen activator (t-PA) concentration and plasminogen activator inhibitor (PAI) activity in aqueous humor of the eye and plasma of blood in patients operated on cataract. MATERIAL AND METHODS: In aqueous humor and citrate plasma of 24 patients undergoing cataract surgery the concentration of t-PA (Imulyse Biopool) and the activity of PAI-1 (Spectrolyse Biopool) were determined. RESULTS: In aqueous humor of 90% patients the concentration of t-PA-Ag in mean value 1.5 +/- 2.7 ng/ml was ca 20% of the level present in plasma. In aqueous humor of nearly all patients no PAI-1 activity could be detected. In a little group of persons because of small amounts of aqueous humor, other fibrinolytic parameters were also estimated and the presence of urokinase-type plasminogen activator (u-PA), alfa-2 antiplasmin (alfa-2AP) and plasmin-alfa-2 antiplasmin (PAP) complexes but no activity of protein C were observed. CONCLUSION: The presence of PAP complexes in aqueous humor indicates on intensive plasminogenesis in vivo. Our examinations confirm the role of fibrinolytic process in physiological and pathological processes occurring in the eye.
