Primary efficacy outcomes included time spent in clinic and patient satisfaction with clinic visits.Results: The 66 participants had mean baseline UCVA of 20/50 in the study eye. Median change in UCVA from baseline to each clinic visit in each arm was “no change”. Mean change in CST was less than 15 microns from baseline to any follow-up clinic visit. Time spent in the clinic at follow-up visits averaged 20 minutes less for participants in the Imaging Only group than those in the Full Exam group. More participants in the Imaging Only group were satisfied with the time spent in clinic and with the clinic visits overall than participants in the Full Exam group: means of 71 vs 91 minutes, respectively, per clinic visit.Conclusion: Based on findings from this randomized pilot study, follow-up retina clinic visits for established patients who have NVAMD and are under treatment with intravitreous injection of anti-VEGF agents could be streamlined by implementing longer intervals between DFE and by relying on imaging alone to make most decisions regarding the need for retreatment, thereby reducing the time spent by patients in clinic and increasing their satisfaction with care received, without excess adverse events.Trial Registration: NCT02251366.Keywords: neovascular age-related macular degeneration, anti-VEGF injection, time in clinic |
