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.
Novel Mechanisms Of Early Age Related Macular Degeneration

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.
The Role Of Estrogen Signalling In The Development And Progress Of Neovascularisation In Macular Degeneration

Summary
Age-related macular degeneration is a common eye disease. In the advanced stages of the disease, abnormal and leaky blood vessels form, causing permanent and severe vision loss. A novel treatment is the application of the sex hormone, estrogen, which could halt abnormal blood vessel growth in the eye. This project aims to confirm the protective effects of estrogen on eye health and whether mutations in estrogen-related genes alter the risk of vision loss due to abnormal blood vessel growth.
The Use Of MicroRNA As Novel Therapeutic Targets For Reducing Retinal Inflammation And Degeneration

Summary
Age-Related Macular Degeneration (AMD) is the most common cause of blindness in Australia. We aim to investigate a new class of potential therapeutics, microRNA which are involved in the regulation of many biological processes, including inflammation. A greater understanding of these miRNA will enable discovery of novel therapeutic targets for inflammatory diseases like AMD, and will have further reaching applications in other inflammatory disease such as Alzheimer’s and Parkinson’s.
Glial-neuronal-vascular Interactions In A Novel Transgenic Model Of Muller Cell Dysfunction

Summary
Muller cell disfunction is a feature shared by many retinal diseases. This project aims to study the contribution of Muller cell dysfunction to retinal neuronal damage and blood-retinal barrier breakdown in a novel transgenic model we recently generated. Results of this study will also be of interest to scientists and clinicians seeking to understand better and treat diseases of the central nervous system in general.
The Role Of Gliosis In Advanced Retinal Degeneration

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.
Investigating MicroRNAs As Key Regulators In A Novel Communication Pathway Driving Retinal Degeneration.

Funding Amount

Summary
Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. The absence of current therapies has resulted in a significant economic burden associated with this debilitating and irreversible disease. This project will investigate the therapeutic potential of the body's own natural delivery vehicles called extracellular vesicles (EV). Along with the molecular cargo contained in EVs we will harness this as a treatment to slow down the progression of AMD.
Determining The Electrical Stimulation Parameters Required To Program The Bionic Eye To Effect Vision.

Summary
Our eyes are invaluable organs that we use for nearly all daily tasks. Loss of vision is devastating but, unfortunately, little can be done at this time. One strategy to restore vision is through a prosthetic to stimulate the retina. For a prosthetic to work, however, we must first understand how the retina encodes the visual image. Our research seeks to decode the retinal signals and determine how a Bionic Eye could be programmed to mimic them.
The Role Of Microglia In Regulating Photoreceptor Integrity

Summary
This project will examine a novel way that photoreceptors in the eye are regulated. In particular, the communication between resident immune cells and photoreceptors will be examined. The results will form an important foundation on which to develop novel treatments for diseases like Age Related Macular Degeneration.
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.
