To determine brain-derived neurotrophic factor (BDNF) levels in the serum and aqueous humor (AH) and assess the relationship between BDNF levels and the thickness of the macular ganglion cell-inner plexiform layer (GCIPL) in macular telangiectasia type 2 (MacTel).This study included 25 patients with MacTel (MacTel group) and 25 control subjects (control group). The levels of BDNF in the serum and AH were tested using an enzyme-binding immunosorbent assay. GCIPL thickness was measured by segmentation analysis using optical coherence tomography (OCT).There was no significant difference in the mean serum BDNF levels between the MacTel and control groups (p = 0.145). The average BDNF level in the AH was significantly lower than that in the control group (p = 0.026). OCT segmentation analyses revealed that the minimum GCIPL thickness was significantly lower in the MacTel group than in the control group (p = 0.039). In the correlation analysis of BDNF levels with GCIPL thickness, significant correlations existed between the BDNF level of the AH and minimum GCIPL thickness in the MacTel group.The concentration of BDNF in the AH was decreased in the MacTel group, and this reduction was related to the minimum GCIPL thickness. The low BDNF levels detected in the MacTel group may have resulted in thinning of the GCIPL due to the loss of retinal ganglion cells. |
