Funding Amount

Summary
Our goal is to determine the numbers and types of nerve cells in the human retina: the part of the eye where visual processing starts. This data will serve as a baseline against which effects of visual disease can be measured.
The Role Of Gliosis In Advanced Retinal Degeneration

Funding Amount
$457,785.00
Summary
The development of treatments that restore vision assumes that the output neurons of the retina remain intact. Yet, there is now considerable evidence that the neurons that signal from the retina to the brain are altered in those that have degenerative diseases of the retina. Here, we will examine the cause of these cellular changes in an animal model and seek to prevent the loss of output neurons. This information is crucial for the development of treatments that seeks to restore vision.
Novel Functional Imaging For Age-related Macular Degeneration

Funding Amount
$564,848.00
Summary
Age-related macular degeneration (AMD) is an eye condition which affects the central retina (the macula) resulting in a loss of central vision. The lack of appropriate clinical tests to monitor the progression of AMD at the early stages of disease hampers the discovery of novel interventions aimed at preventing the development of advanced vision-threatening AMD. In this project, we will investigate the use of a quick and non-invasive imaging technique for monitoring AMD progression.

Summary
Age Related Macular degeneration (AMD) is a leading cause of blindness in Australia. In this project we will examine a novel mechanism by which the cells at the back of the eye, called retinal pigment eptihelial cells contribute to vision loss early in the disease. In addition we will examine the potential for two currently used drugs as well as a novel laser treatment in slowing the progression of disease.
Understanding the structure of the human retina is important for understanding normal visual function. The goal of this study is to supply data on the distribution, density and connectivity of nerve cells in the human retina. Our study will provide a foundation for areas of clinical investigation of the human retina.
We will investigate changes in the retina secondary to disease process and try and modify them to allow a longer time frame for intervention. These changes (remodelling) are detrimental to visual function and the effectiveness of measures aimed at restoring vision, eg, bionic eye.
The Role Of Microglia In Early Diabetic Retinopathy

Funding Amount
$665,582.00
Summary
Diabetic retinopathy is one of the most feared complications of diabetes. This project will examine the role that retinal immune cells called microglia have in causing early changes in the vasculature. We will examine whether diabetes changes the way neurons communicate with blood vessels, opening up a possible treatment target that could prevent the progression to more advanced disease.
Improving Inner Retinal Oxygenation: Developing A New Form Of Retinal Laser Photocoagulation Therapy
Funder

Funding Amount
$408,818.00
Summary
Diabetic retinopathy is the major cause of vision loss in the working age population in our community. Current therapy involves laser destruction of much of the peripheral retina to protect the central vision. However, recent clinical and experimental evidence suggests that more moderate laser therapy could be sufficient, and that useful vision in the laser treated area can be preserved. Benefits to the patient would include reduced loss of visual field, and reduced night blindness.
The Contribution Of Aberrant Wnt Signalling To Neuronal And Vascular Pathology In Retinal Disease

Funding Amount
$561,342.00
Summary
Neuronal damage and vascular abnormalities are features shared by many retinal diseases. We will use a novel transgenic model to study the contributions of aberrant Wnt signalling in retinal neuronal and vascular pathology, and also, to test strategies for neuroprotection and inhibition of vascular abnormalities. Success in the project may identify novel therapeutic targets leading to safer and more effective treatments for retinal diseases.
Role Of Dendritic Information Processing In Visual Circuit Computations

Funding Amount
$895,244.00
Summary
Vision is the primary sensory modality in man, and its disturbance carries an enormous socio-economic burden. The dynamic operations of the neuronal assemblies that underlie vision are poorly understood, partly because of an incomplete description of the computational properties of visual neuronal circuits. The aims of the application are to mechanistically dissect defined computational operations of visual neural circuits using advanced electrophysiological and optical recording techniques.
