Targeting At Risk Relatives Of Glaucoma Patients For Early Diagnosis And Treatment (TARRGET)

Summary
Glaucoma is the second leading cause of blindness in Australia but early detection and treatment can prevent blindness. We will recruit patients with advanced glaucoma from an Australia wide registry and refer their close relatives to have an eye exam and genetic testing to see if they are at risk of glaucoma. We will evaluate how a coordinator can improve the uptake of this screening program referring people to local eye care providers and in rural WA providing screening in 16 remote locations.
Saving The Optic Nerve : Manipulating The Shp2-Caveolin Axis

Summary
Glaucoma is a leading cause of blindness with many patients experiencing progressive vision loss despite treatment. We propose to use gene therapy techniques to manipulate the signalling pathway of Brain Derived Neurotrophic Factor and its receptor, along with biochemical and functional approaches to understand the mechanisms of glaucoma mediated eye damage and to develop new therapeutic strategies.
Translating Genetic Determinants Of Glaucoma Into Better Diagnosis And Treatment

Summary
Glaucoma is the leading cause of irreversible blindness worldwide. By 2020, it will affect 80 million people, and in Australia over the next decade, the overall cost of glaucoma will reach $4.3 billion per annum. This Program will use genetic advances to personalise treatment. Blindness will be prevented in individuals at highest risk, new ways to treat patients will be developed, and better outcomes for patients will result from less treatment and monitoring of low risk cases.
Harnessing Anticalin Technology As A Multi-targeted Treament Approach For Vision Loss

Summary
Diabetes is a leading cause of vision loss and blindness worldwide and is caused by two factors called VEGF and Ang2, which damage blood vessels. Current treatments only block VEGF and many patients do not respond and suffer irreversible damage to sight. We have used ground-breaking anticalin technology to make a new drug (PRS-AUS1) that blocks both VEGF and Ang2. Studies will be performed in animal models and move to patients where we expect improved outcomes compared to current treatments.
Young Adult Myopia: Genetic And Environmental Associations

Funding Amount

Summary
Myopia affects 80% of school leavers in the cities of East Asia, 45% of Asian Australian school leavers and is probably on the rise in European Australian adolescents. Increased levels of education and lack of time outdoors are known to increase the risk of myopia. We will examine 2,000 young adults to find the genes that interact with these risk factors. In addition to confirming when these risk factors are most important, identifying molecular pathways opens the avenue of new treatments.
Seeing Clearly: Examining The Consequences Of Glaucoma For The Human Brain

Summary
Glaucoma is a major cause of blindness. Many people are unaware of the resulting blind region (scotoma) and fail to get an eye test, allowing the disease to progress. This project aims to see how the brain ‘fills in’ the scotoma, and the effect of different scotoma types, using vision tests, brain imaging, and behavioural methods. The results will tell us whether the region around a scotoma helps or hinders the person's remaining vision, which is critical for activities such as driving.
Centre-surround interactions in ageing human vision. Australia has a rapidly ageing population. This project will study how ageing affects the visual perception of objects presented on non-uniform backgrounds. Our ability to discriminate objects from their backgrounds is key to most natural visual tasks. The visual processes involved are known as centre-surround interactions, and are considered fundamental building blocks to human perception. This project will significantly advance our knowledge ....Centre-surround interactions in ageing human vision. Australia has a rapidly ageing population. This project will study how ageing affects the visual perception of objects presented on non-uniform backgrounds. Our ability to discriminate objects from their backgrounds is key to most natural visual tasks. The visual processes involved are known as centre-surround interactions, and are considered fundamental building blocks to human perception. This project will significantly advance our knowledge of which spatial visual mechanisms are altered due to age, supplying key information for understanding and improving visual environments for the elderly, as well as increasing knowledge of the brain mechanisms susceptible to the ageing process.Read moreRead less
Neural plasticity in older adult human vision. This project aims to expand our understanding of age related changes in brain function, specifically plasticity. The project will increase knowledge of the role of an inhibitory neurotransmitter GABA in visual plasticity. Expected outcomes include new knowledge regarding the regulation of brain function in adulthood, enabling future research and planning for societal benefit to older Australia.
Wiring the retina for human vision - a single-cell behavioural approach. This project aims to combine optical and behavioural methods to explore how colour information is channelled from individual cone photoreceptors through the living human retina, to the brain. By non-invasively stimulating either a single cell or specific arrangements of cells, the project aims to contribute fundamental knowledge about how the retina is wired to inform our exquisite sense of colour and spatial vision. This u ....Wiring the retina for human vision - a single-cell behavioural approach. This project aims to combine optical and behavioural methods to explore how colour information is channelled from individual cone photoreceptors through the living human retina, to the brain. By non-invasively stimulating either a single cell or specific arrangements of cells, the project aims to contribute fundamental knowledge about how the retina is wired to inform our exquisite sense of colour and spatial vision. This understanding has consequences across a range of disciplines, including artificial vision systems such as driverless cars, retinal disease, and the processing of information through neuronal connections in general.Read moreRead less
The mechanism for defocus-driven ocular growth. 30 per cent of the Australian young adult population (with much higher percentages in Asia) suffer from myopia, and while we know the retina senses defocus, we do not know how. The knowledge gained through this project will help the development of pharmaceuticals to control myopia and of developmental practices that minimise the chances of children becoming myopic.
