Evaluation of Aqueous Endocan and Endostatin Levels in Patients With Pseudoexfoliation Syndrome

Abstract

Purpose: The purpose of the present study was to evaluate the aqueous humor endocan and endostatin levels in patients with pseudoexfoliation (PEX) syndrome and to compare the results with healthy individuals. Materials and Methods: Twenty nine cataract patients with PEX syndrome (PEX group) and 32 cataract patients without PEX syndrome (control group) were enrolled in the study. Endocan and endostatin were measured in the aqueous humor of the PEX and control groups by enzyme-linked immunosorbent assay. Results: There was no difference between the PEX and control groups in terms of age (P=0.721) and sex (P=0.902). The aqueous levels of endocan in patients with PEX (26.39 +/- 5.80 pg/mL) was significantly higher than in the control group (11.42 +/- 2.44 pg/mL) (P=0.039). The aqueous levels of endostatin was 12.00 +/- 1.35 ng/mL in the PEX group and 14.22 +/- 3.31 ng/mL in the control group, however, the difference was not statistically significant (P=0.41). Conclusions: The findings of the present study could suggest that the increased levels of aqueous endocan may be related to pathogenesis of PEX. However, levels of aqueous endostatin did not show any significant difference in PEX.
