Key Points

The research aims to understand the optical effects of hyporeflective core drusen on Bruch's membrane as seen in OCT images.
Analysis of OCT images regarding the bending of Bruch's membrane
Assessment of optical properties associated with hyporeflective core drusen
Proposed new quantitative metrics for improved analysis
Hyporeflective core drusen induce an artifactual bending of Bruch's membrane on OCT images.
This bending can affect the quantitation of choroidal features in OCT.
Insights gained may enhance knowledge of age-related macular degeneration (AMD).

Abstract

BM bending induced by hypoRCD is an artifactual OCT feature that reflects the optical properties of the hypoRCs. This morphological characteristic may improve our understanding of hypoRCD, raise cautions in quantitation of CCFDs under hypoRCD, and provide additional insights into their role in AMD.
