IT’S TIME TO SEE GEOGRAPHIC
ATROPHY DIFFERENTLY

Geographic atrophy (GA) is an advanced form of dry age-related macular degeneration (AMD) that causes irreversible vision loss.1

GA Has a Devastating Impact on Patients’ Lives2

GA can progress from the noncentral area to the foveal center point in just 2.5 years from diagnosis and currently affects ∼5 million people worldwide.1,5

Imaging: Diagnosis and Progression

Imaging: Diagnosis and Progression

Imaging plays a critical role in both the early diagnosis of GA and in the monitoring of disease progression.5

The Role of the Complement System

The Role of the Complement System


Dysregulation of the complement system has been strongly associated with the progression and pathogenesis of GA.6,7


*Findings from a UK retrospective cohort analysis with patients with visual acuity (VA) follow-up. The patients were eligible to drive at baseline according to the UK driving standard (VA measure >70 letters or Snellen 6/12 [US Snellen 20/40] in the better-seeing eye) but lost their vision progressively making them ineligible to drive; 1.6 years represents the median (0.7-2.7 years).8

†Analysis of the Chroma, Spectri, and Proxima A trials, including 2006 patients with GA.4
