Comparison of Total Oxidative Stress, Total Antioxidant Capacity, and Paraoxonase, Arylesterase, and Lipid Peroxidase Levels in Aqueous Humor and Serum of Diabetic and Non-Diabetic Patients with Catarac
Pur po se: The aim was to compare total oxidative stress (TOS), total antioxidant capacity (TAC), and paraoxonase (PON1), arylesterase (ARE), and lipid peroxidase (LPO) levels in the aqueous humor and concurrent venous blood serum and to evaluate the role of oxidative stress in the progression of...

description | Pur po se: The aim was to compare total oxidative stress (TOS), total antioxidant capacity (TAC), and paraoxonase (PON1), arylesterase
(ARE), and lipid peroxidase (LPO) levels in the aqueous humor and concurrent venous blood serum and to evaluate the role of oxidative
stress in the progression of diabetic retinopathy in diabetic and non-diabetic patients with cataract.
Ma te ri al and Met hod: Oxidative tissue and organ damage play a significant role in diabetes and related complications. A reduction in the
activities of antioxidant enzymes such as superoxide dismutase, glutathione peroxidase, glutathione reductase and catalase has been reported in
both blood and lens samples. PON1, ARE, and LPO are unreviewed antioxidant enzymes until now. We included diabetic and non-diabetic
patients who were admitted to our clinic for complaints of hazy vision and who received the diagnosis of cataract. Patients were divided into 3
groups: group 1 - diabetic patients without retinopathy, group 2- with diabetic retinopathy, and group 3 - patients without systemic disease
outside the diagnosis of cataract. A total of 78 patients (26 patients in each group) were enrolled in the study.
Re sults: In this study, there was no statistically significant difference among the groups for TOS, TAC, PON1, ARE and LPO levels in
aqueous humor. Although simultaneous venous blood serum results, TOS, TAC, PON1 and HbA1c levels in all 3 groups were found
statistically significant, ARE and LPO were not statistically significant. When groups 1 and 2 were compared with control group, it was
found that in group 1, PON 1 was statistically significantly low and HbA1c was high, while in group 2, TOS and HbA1c were high and
TAC and PON 1 were low (p<0.05).
Dis cus si on: Oxidative stress indicator enzymes were determined to be positive in blood and negative in humor aquosus. In the present
study, these enzymes were studied for the first time in aqueous humor, thus, further studies including subtypes in case of polymorphism are
needed. (Turk J Ophthalmol 2012; 42: 47-52) |
