Understanding Geographic Atrophy

A CLOSER LOOK AT ADVANCED AMD

Age-related macular degeneration (AMD) is a leading cause of blindness in people age 50 and older. Geographic atrophy, an advanced form of AMD, can have a devastating impact on vision.1

an Unmet Need
More than 5 million people worldwide have geographic atrophy,2
including nearly 1 million people in the U.S.7

In developed nations, approximately 1 in 29 people over age 75 have geographic atrophy, 3,4,5
which increases to nearly 1 in 4 people over age 90.6
Impact on Vision
42% of patients’ eyes with geographic atrophy are legally blind (20/200 or worse with best correction).8,9
Healthy vision is 20/20
29% of patients’ eyes with geographic atrophy had ≥6 lines of vision loss on an eye chart by 4 years10

SEEING FACES
DRIVING
READING AND WRITING
COOKING
What’s Happening in Your Eye?

AMD causes damage to the macula – the part of the eye that provides sharp, central vision1


In geographic atrophy:11

  • A dark spot appears in central or peripheral vision
  • Colors seem dull or washed out
  • Vision becomes less sharp or detailed
  • Seeing in the dark becomes difficult
NORMAL VISION
VISION WITH GEOGRAPHIC ATROPHY

If you notice any of the symptoms of geographic atrophy, you should speak to your physician. A comprehensive eye exam can be used to diagnose and monitor AMD and geographic atrophy1

Family History and Other AMD Risk Factors

Genetics – a family history increases the risk of AMD

With family history: 50% risk
No family history: 12% risk12
A recent study identified 19 genetic markers associated with AMD risk13

Other AMD risk factors:

AGE
SMOKING NEARLY DOUBLES THE RISK
OBESITY INCREASES THE RISK FOR ADVANCED AMD14
CARDIOVASCULAR DISEASE15
RACE – MORE COMMON AMONG CAUCASIANS
What Can Be Done for Geographic Atrophy?

There are currently no treatments available to slow the progression of geographic atrophy

Clinical trials are underway for potential geographic atrophy treatments
Low vision aids like magnifiers or special eyeglasses may also be prescribed
