Abstract

Objective
To describe the spatial and temporal characteristics of hyperreflective material (HRM) on spectral-domain OCT (SD-OCT) in neovascular age-related macular degeneration (nAMD) during antiangiogenic treatment and explore associations with best-corrected visual acuity (BCVA) and macular atrophy (MA).

Design
Retrospective regrading of SD-OCT-images from the multicenter, randomized controlled AVENUE trial (NCT02484690, conducted from August 2015 to September 2017).

Participants
Treatment-naive nAMD patients enrolled from 50 sites in the US.

Methods
Retrospective regrading and secondary analysis.

Main Outcome Measures
Spectral-domain OCT images from 207 study eyes that fit criteria for the present analysis were graded for HRM features, its evolution, and associated hypertransmission into choroid (HTC), a proxy for MA. The appearance of a well-defined hyperreflective inner boundary that separated persistent HRM from the neurosensory retina continuous with the adjacent retinal pigment epithelium layer was defined as hyperreflective material boundary remodeling (HRM-BR). Patterns of HRM composition/evolution were defined as follows: (1) no subretinal HRM at baseline, (2) fully resolved, (3) persistent with complete HRM-BR, or (4) partial/absent HRM-BR. Associations of HRM patterns with BCVA and HTC were analyzed. Predictive factors for complete HRM-BR were explored.

Results
Of 207 included eyes, subretinal HRM was present in 159 (76.8%) at baseline and persisted until month 9 in 118 (57.0%) eyes. Of these 118 eyes, 44.9% developed complete HRM-BR and had similar BCVA outcomes by month 9 compared with no/fully resolved subretinal HRM. Partial/absent HRM-BR had a strong negative association with BCVA outcome (−6.1 ETDRS letters; P = 0.016) and a higher frequency of intralesional HTC (69.2%) compared with eyes with complete HRM-BR (20.8%) at month 9. Older age (odds ratio [OR], 0.96; P = 0.054) and presence of intralesional HTC (OR, 0.06; P = 0.010) at baseline were associated with lower odds of complete HRM-BR at month 9.

Conclusions
In nAMD eyes under antiangiogenic treatment, complete HRM-BR occurred frequently and was associated with better BCVA than when HRM-BR was only partial/absent.
