About this trial
This monocentric prospective longitudinal observational study will validate fundus-tracked dark adaptometry as an endpoint for future treatment trials in early and intermediate age-related macular degeneration (AMD). The study will characterize normative cone- and rod-mediated dark adaptation parameters in healthy volunteers, assess test-retest reliability, quantify sensitivity to change over time, evaluate diagnostic and prognostic validity against AMD stage and structural progression, and investigate imaging-, biomarker-, and genetics-based determinants of impaired dark adaptation.
