Abstract
Purpose :
To elucidate the effects of intravitreal faricimab 6.0 mg on functional and anatomic outcomes in previously treated patients with neovascular age-related macular degeneration (nAMD).
Methods :
Retrospective chart review was performed on nAMD patients previously treated with intravitreal bevacizumab, ranibizumab, and/or aflibercept who received ≥1 injection of intravitreal faricimab 6.0 mg. Exclusion criteria included patients with secondary causes of choroidal neovascularization such as myopic degeneration, polypoidal choroid vasculopathy, trauma, and idiopathic. Fibrovascular pigment epithelial detachment (fvPED) height was measured by two independent graders using the foveal horizontal raster on OCT capturing the maximum height of the fvPED from Bruch’s membrane to the outer margin of the hyperreflective RPE layer. Central foveal thickness (CFT) was measured from the internal limiting membrane (ILM) to Bruch’s membrane. Image J software was used to analyze OCT images. Paired t-tests were used to compare the mean logarithm of minimum angle of resolution visual acuity (logMAR VA), fvPED height (µ) and CFT (µ) at the baseline visit at which the first faricimab injection was given and at the final visit after receiving the last faricimab intravitreal injection(s).
Results :
240 patients met inclusion criteria. Preliminary analyses of 32 eyes of 31 patients were performed. Median age was 83.5 years, 58% (18/31) were female, and 90% (28/31) were pseudophakic. The median number of intravitreal injections received prior to the first faricimab 6.0 mg injection was 48.5 (mean 53 ± 34). The median number of faricimab 6.0 mg injectons received was 3 (mean 3.2 ±1.4). Mean logMAR VA at baseline was 0.74±0.67 (~20/110), and final mean logMAR VA was 0.70±0.68 (~20/100) [p = 0.53]. Mean fvPED height was 181 μ at baseline which decreased to 162 μ at the final visit (p=0.002). Mean CFT was 379 μ at baseline and 357 μ at the final visit (p=0.20).
Conclusions :
A statistically significant decrease in fvPED height was found after at least one intravitreal faricimab 6.0 mg injection in patients with previously treated nAMD. Further data analysis is required to verify these results.
