Abstract
The concentration of .alpha.2-macroglobulin, .alpha.1-antitrypsin, plasminogen, C3-complement, fibrinogen degradation products (FDP) and fibrinolytic activity were studied in the aqueous humor and serum from 9 patients with Fuchs'' endothelial dystrophy, 17 patients with uncomplicated senile cataract, and in the secondary aqueous from 6 cataract patients. Finally, the aqueous humor and serum from 2 patients with anterior uveitis were studied. An increased concentration of .alpha.2-macroglobulin, .alpha.1-antitrypsin, plasminogen and C3-complement was found in both the aqueous and the serum from patients with Fuchs'' dystrophy when compared with the primary aqueous and serum from patients with cataract, but this was only significant for .alpha.1-antitrypsin in aqueous humor. A significant increase in the amount of FDP was found in the serum of the Fuchs'' patients compared with the cataract patients. Fibrinolytic activity could not be demonstrated in the serum in any of the patient groups. The concentrations of the various factors found in the secondary aqueous of the cataract patients differed only slightly from the content of the primary aqueous of the Fuchs'' patients.
