Investigating Macular Tissue Integrity Index as a Novel Biomarker in Geographic Atrophy
2 Jul 2025
Abstract excerpt
Purpose: The rate of geographic atrophy (GA) enlargement is commonly used as an outcome in clinical trials. However, this metric typically lacks specificity for central macular involvement and structure-function relationships. We propose a targeted approach in monitoring GA progression within the central macula, highlighting the limited benefit of including GA expansion beyond the 3-mm perifoveal zone when...
