IMPACT OF RETINAL FLUID-FREE MONTHS ON OUTCOMES IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION: A Treatment Agnostic...

To assess the effect of the total number of fluid-free months after loading on visual and anatomical outcomes in neovascular age-related macular degeneration patients receiving anti-vascular endothelial growth factor therapy.

This post hoc analysis pooled patient-level data from the brolucizumab 6 mg (n = 718) and aflibercept 2 mg (n = 715) arms of the HAWK and HARRIER randomized clinical trials. Based on data from Weeks 12 to 96, patients were assigned to one of five categories based on fluid-free visits (FFVs; the total number of monthly visits at which they were observed to be without retinal fluid). Three definitions of "fluid-free" were explored based on the location of the fluid observed.

Patients allocated to Categories 4 (15-21 FFV) and 5 (22 FFV, always dry) consistently had the best visual and anatomical outcomes at Week 96, whereas patients allocated to Categories 1 (0 FFV, never dry) and 2 (1-7 FFV) consistently had the worst visual and anatomical outcomes. Variability in retinal thickness over time was lowest in Categories 4 and 5.

Absence of retinal fluid at more visits after loading has a positive association with visual and anatomic outcomes in neovascular age-related macular degeneration patients, regardless of fluid type.
