Thiol-Disulfide Homeostasis and Serum Ischemia Modified Albumin Levels in Patients with Primary Open-Angle Glaucoma.
Aim: Glaucoma is an optic neuropathy causing progressive impairment of visual functions. We aimed to assess the alterations in thiol-disulfide homeostasis and serum ischemia modified albumin (IMA) levels, which are the determinants of antioxidant status, in patients with primary open-angle glaucoma (POAG). Material and Method: A total of 140 eyes from 70 patients with POAG and 174 eyes of 87 healthy, control cases were included in the study. ⋯ Conclusion: In patients with POAG, thiol-disulfide homeostasis is disturbed in the favor of pro-oxidant molecules and IMA levels are increased, indicating the presence of augmented oxidative stress. In that aspect, systemic and local anti-oxidant treatments may be new targets in glaucoma treatment. Larger, prospective studies about the role of anti-oxidants in prevention and treatment of POAG are warranted.
