Summary
Age-related macular degeneration (AMD) is a progressive disease, commencing with the less severe age-related maculopathy (ARM), that ultimately can lead to the loss of fine central vision and personal independence. People with advanced AMD generally retain some mobility if their peripheral vision is maintained, but they are unable to perform tasks such as reading, hobbies or recognising people's faces. Unfortunately, the available treatment for AMD, macular laser photocoagulation, benefits only ....Age-related macular degeneration (AMD) is a progressive disease, commencing with the less severe age-related maculopathy (ARM), that ultimately can lead to the loss of fine central vision and personal independence. People with advanced AMD generally retain some mobility if their peripheral vision is maintained, but they are unable to perform tasks such as reading, hobbies or recognising people's faces. Unfortunately, the available treatment for AMD, macular laser photocoagulation, benefits only a minority of people with this disease. Until safe and effective treatments for AMD can be developed, identification of major risk factors for the development and progression of AMD is essential to determine if interventions aimed at primary prevention can be initiated. This project will expand on the initial findings of the Visual Impairment Project (VIP), a population-based study of age-related eye disease in a cohort of more than 5000 Victorians aged 40 years and older. Data from the VIP have shown that AMD is the most important ophthalmologic public health problem, particularly since AMD is the major cause of vision impairment in Australia and has the least available treatment options. This study will follow individuals who were identified in the VIP with ARM-AMD to determine the natural history and risk factors associated with the longer term progression of AMD. Particular emphasis will be on determining the role of cardiovascular disease risk factors in AMD progression.Read moreRead less
Genes And Environment In The Risk Of Early Age-Related Macular Degeneration: A Population-based Case-Control Study

Summary
This study will pool data from three well-conducted population-based cohorts of older persons to gain a large sample size in order to investigate the interplay of genes and environmental factors on the risk of age-related macular degeneration (AMD). The study will give insights into AMD pathogenesis, and enable potential targeting of people with AMD susceptibility genes for preventive approaches. These could ultimately reduce the burden of this blinding condition.
Genes And Environment In Late AMD: Pooling A State And Population Resource

Summary
This study will pool cases from the West Australian Macular Degeneration database with the Blue Mountains Eye Study (NSW), to investigate the interplay of genes and environmental factors on risk of age-related macular degeneration (AMD), in particular the late, vision threatening stage. It will provide insights into the underlying causes of AMD, and could allow us to target people with AMD susceptibility genes for preventive approaches, which could reduce the burden of this disease.
