GA may impact patients sooner than you expect
Every year, patients with GA can experience further disease progression and loss of photoreceptors, resulting in changes to visual function that can affect daily activities and may ultimately lead to loss of independence.4-6,8
Early detection means early protection
A comprehensive eye examination with imaging can help with early detection, diagnosis, and monitoring of GA. GA is a heterogeneous disease, so it’s important to be vigilant and look for key biomarkers in the imaging modalities you have in your office.
Color Fundus Photography (CFP)
- Sharply demarcated, typically circular zone with increased choroidal vessel visibility
Fundus Autofluorescence (FAF)
- Hypofluorescence with a sharply demarcated border
- Hyperfluorescence surrounding atrophic lesion can indicate lipofuscin accumulation and prognostic of GA progression
