Brief summary
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss worldwide, and nearly two million Australians have some signs of AMD. This proposed project is a prospective, observational study that seeks to to understand the underlying aetiology of AMD, factors associated with differences between age-related macular degeneration (AMD) phenotypes or severities, or between AMD and healthy individuals. It also seeks to understand the natural history of AMD progression and the factors associated with the rate of progression. In this project, the disease phenotype, genotype and severity and rate of progression will be determined based on non-invasive clinical imaging or functional assessment of the retina, from obtaining biological samples from the participants, or from patient-reported outcomes.

Inclusion criteria
1. 18 years of age or older; and 2. either AMD (defined as having at least a medium druse \>63 um), or having eyes with normal ageing changes (including small drusen ≤63 um) or no abnormalities as control participants
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Investigate the underlying aetiology of Age-Related Macular Degeneration | Up to 20 years | The first aim of this project is to comprehensively investigate the underlying aetiology of AMD, characterise the AMD phenotype by understanding the differences between those with AMD and healthy individuals. |
| Characterise the natural history of Age-Related Macular Degeneration and factors associated with its rate of progression. | Up to 20 years | The second aim of this project is to characterise the natural history of AMD and factors associated with its rate of progression. These aims will be achieved by using performing imaging and functional assessment of the retina, characterisation of the genetic, systemic and environmental factors, and by obtaining patient-reported outcomes. |
