Abstract
Purpose :
To evaluate visual outcome and retinal function, assessed with multifocal electroretinography (mfERG) and full-field electroretinography (ffERG), in eyes treated with Aflibercept for neovascular age-related macular degeneration (nAMD).
Methods :
This prospective pilot study included 29 eyes of 29 treatment-naïve patients (mean age 79 ±8 years) with nAMD. We examined visual acuity (VA), optical coherence tomography (OCT), mfERG and ffERG prior to intravitreal treatment with Aflibercept and at 6 months follow-up.
Results :
We showed significant improvement in mean VA from 65 ±13 to 71 ±17 letters (p=0.001) as well as a decrease of central retinal thickness from 300 ±80 μm to 222 ±37 μm (p<0.001). The decrease in OCT values correlated well to the improvement of VA; r=-0.63, p<0.001. The patients received mean 4.7 ±0.5 injections. FfERG 30-Hz flicker indicated an increase in cone photoreceptor function with a mean amplitude change from 43.9 ±15.0 μV to 49.4 ±18.9 μV (p=0.005). Implicit time was generally prolonged compared to healthy individuals, but was stable from baseline to follow-up; 33.85 ±2.75 ms at baseline and 33.83 ±2.63 ms after 6 months of treatment. No difference was demonstrated in neither MfERG amplitudes nor implicit time from baseline to follow-up.
Conclusions :
Retinal function improved, assessed with 30-HZ flicker, in patients treated with Aflibercept for nAMD after six months follow-up. Visual Acuity outcome correlated well to the decrease of central retinal thickness.
