The Unmet Patient Need

The time is now

Geographic Atrophy (GA) Affects More People Than You Realize

Age-related macular degeneration (AMD) advances to GA, which can cause irreversible vision loss.1,2

GA affects ~5 million people worldwide3

GA is expected to affect more than 18 million people worldwide by 20404,5

People with GA typically lose their vision within 2.5 years6

Once vision is affected by GA, change is irreversible—early diagnosis is an important first step in seeking to minimize disease impact.

Visual Acuity ≠ Visual Function

Monitoring for progression can be difficult since disease progression is NOT always correlated with a decline in visual acuity, particularly with extrafoveal lesions.

To get a complete look at how GA is impacting your patients, you can go beyond best corrected visual acuity (BCVA) by evaluating functional assessments.3,7

Functional Tests to Assess GA
Contrast Sensitivity

Contrast Sensitivity

May be used to detect abnormal visual function in patients with good BCVA3

Low-Light Visual Acuity (LLVA)

Low-Light Visual Acuity (LLVA)

Deficits in LLVA are associated with higher GA lesion progression rates7

Dark Adaptation

Dark Adaptation

Delayed dark adaptation may provide evidence of age-related macular degeneration (AMD) before the appearance of clinical features, such as drusen and focal pigmentary changes2,8

Microperimetry

Microperimetry

A decrease in retinal sensitivity can correlate with lesion enlargement over time7,9

Fear of Vision Loss

Patients with GA fear missing out on important life events and losing their independence.10,11

Patients Suffer From

Distorted vision,12 scotoma,13 and photopsia13

Central field defect12

Vision loss13

Which Leads to Patients Worrying About

Missing meaningful life events10,11,14,15

Being unable to complete everyday tasks15,16

Loss of independence (eg, difficulty driving)11,14-16

GA Changes Lives

Emerging therapies may offer eye care professionals the opportunity to slow the progression of GA and help patients address some of the biggest obstacles they face in their daily lives.7

Patients Lose More Than Just Vision

Reported difficulty reading for everyday tasks or leisure16

Lose confidence driving at night15

Will lose their ability to drive within 1.6 years after diagnosis11
