Biomarkers, Imaging, and Early Treatment Decisions in Geographic Atrophy

Which imaging biomarkers matter most at diagnosis of GA, and how should they shape the decision to treat? In episode 1 of the GA in Practice miniseries on New Retina Radio, moderator Geeta Lalwani, MD, and panelists Murtaza Adam, MD, and Carl Danzig, MD, review the practical role of fundus autofluorescence and OCT in identifying high-risk GA, discuss ellipsoid zone integrity as an emerging endpoint, and work through a hypothetical case of an active, motivated patient with bilateral extrafoveal GA and good vision to explore how lifestyle, lesion characteristics, and patient education factor into early treatment decisions.
