Geographic atrophy progression is constant and irreversible

Geographic atrophy impairs functional vision with a substantial impact on patients’ independence and quality of life, and gradually leads to irreversible vision loss.1,2

Geographic Atrophy

The impact of geographic atrophy

Geographic atrophy is the advanced stage of dry age-related macular degeneration (AMD) and is characterised by progressive and irreversible loss of the photoreceptors, retinal pigment epithelium (RPE) and the underlying choriocapillaris.3

With no approved treatments available, it is a significant unmet medical need in ophthalmology.4

Geographic atrophy (GA) and advanced dry AMD

are both terms used to describe the advanced form of dry age-related macular degeneration (AMD), which is a leading cause of blindness worldwide.3,5

Over 5 million people worldwide are affected by geographic atrophy, with prevalence increasing with age.6 Geographic atrophy has a significant and negative impact on vision and quality of life.7 - 5 million people are affected by Geographic Atrophy

Complement overactivation

has been detected systemically in age-related macular degeneration (AMD) and locally in patients with geographic atrophy.8

Are you looking for supportive patient materials? - dryAMD logo is a website dedicated to providing information and support
to those affected by geographic atrophy or advanced dry age-related macular degeneration (AMD), as well as those who care for them.

The website has been created with patients living with blindness to ensure that it truly meets the needs of people with age-related macular degeneration. - Infographics icon
