Outline of Final Research Achievements |
Glaucoma (PG) is characterized as progressive glaucomatous optic neuropathy leading to visual field loss. It is a cause of irreversible blindness worldwide. We proposed totally assessed hydroxylinoleates (HODEs) from biological samples as biomarkers for investigations of pathogenesis, disease progression, and prognosis. HODEs consist of six isomers that are yielded by a radical, singlet oxygen and enzymes oxidation. In the present study, we investigated the involvement of oxidative stress in this disease by using our own proposed oxidative stress marker HODEs quantitatively. PG patients (n = 198) were recruited depending on intraocular pressure (IOP). In the PG group, serum levels of HODEs demonstrated higher levels than those in the cataract (CT) group. Furthermore, HODEs levels increased with the increase in IOP, suggesting that the systemic oxidation is involved in PG at least partially.
