Tear Film and Serum Prolidase Activity and Oxidative Stress in Patients With Keratoconus

Abstract

The serum PA was found to be lower in patients with keratoconus than in the controls. Additionally, serum oxidative stress markers were found to be higher than those of the controls. Thus, prolidase and systemic oxidative stress may have a role in the pathogenesis of keratoconus.
