Reduced Plasma BDNF Levels in Normal Tension Glaucoma Compared to Open Angle Glaucoma.

The study suggests that a low level of systemic BDNF may contribute to the pathogenesis of glaucoma in an IOP-independent manner. To evaluate differences in systemic brain-derived neurotrophic factor (BDNF) levels between primary open angle glaucoma (POAG) patients and normal tension glaucoma (NTG) patients. This study collected blood samples from 260 NTG patients, 220 age-matched POAG patients, and 120 age-matched cataract patients (as controls). BDNF levels were measured with an antibody-conjugated bead assay system (Luminex). We found that plasma BDNF levels in the NTG group were significantly lower than in the POAG and cataract control groups. There was no significant difference between the POAG and cataract groups. This result suggests that a low level of systemic BDNF may contribute to the pathogenesis of glaucoma in an IOP-independent manner. Copyright © 2023 The Author(s).
