| Summary: | Abstract This study aimed to evaluate the changes in cytokine levels in the aqueous humor and factors of treatment resistance following intravitreal faricimab injection in treatment-naïve patients with neovascular age-related macular degeneration. A total of 32 eyes were analyzed before and after a single faricimab injection. Although the best-corrected visual acuity (BCVA) showed no significant improvement, the mean central retinal thickness decreased significantly by 73.7% (P < 0.01), and more than 90% of the eyes showed improvement in exudative changes 1 month after faricimab injection. Moreover, the aqueous humor concentrations of vascular endothelial growth factor (VEGF)-A, angiopoietin (Ang)-2, and placental growth factor considerably decreased 1 month after faricimab injection. Multivariate analyses adjusted for age, sex, BCVA, central choroidal thickness, and aqueous humor cytokines revealed that higher Ang-2 levels in the aqueous humor at baseline were associated with better treatment response to faricimab injection. These findings suggest that the dual inhibition of VEGF-A and Ang-2 by faricimab is effective in reducing exudative changes and that Ang-2 may serve as a potential biomarker for predicting faricimab treatment response. |
