This course examines geographic atrophy (GA) with an emphasis on clinically actionable diagnosis and management. Participants will review disease mechanisms, risk factors, staging, symptoms, and natural history; apply multimodal imaging and OCT biomarkers to identify atrophy and estimate progression risk; and compare the efficacy, safety and burden associated with approved complement inhibitors. The course concludes with practical referral and counseling strategies and a review of emerging therapies, including photobiomodulation and investigational complement and neuroprotective approaches.
