Raised Intracranial Pressure After Trauma: Characterisation And Development Of Pharmacological Interventions

Funding Amount
$589,788.00
Summary
Raised intracranial pressure (ICP) commonly occurs after traumatic brain injury (TBI) and is thought to be responsible for up to 50% of all mortality, as well as significantly contributing to the persistent neurological deficits in survivors. Few studies have examined the dynamics of raised ICP after TBI, or its effects on brain oxygenation. This study will fully characterize changes in ICP and brain oxygen after TBI and develop novel treatments to control such changes.
The Cellular Organisation Of Interneurones In Human Retina

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.
Retinal Endothelial Cell Changes That Precede Retinal Vein Occlusion And The Retinal Extracellular Space Changes That Follow It

Summary
Dr. Min Hye Kang, at The University of Western Australia, is investigating microscopic blood vessel changes that precede the onset of devastating blindness. She is also studying functional changes that occur in the retina following deprivation of its blood supply. Her research has significantly improved our understanding of cellular mechanisms that lead to blindness. It has also aided in the development of new treatment strategies for the prevention of vision loss.
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.
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.
How Does Glucose Protect The Retina And Optic Nerve Against Ischaemia?

Funding Amount
$418,171.00
Summary
Raised blood sugar levels are generally considered to be bad for nerve cells, especially those in the eye. But we have made a groundbreaking discovery finding that in the short-term, sugar can rescue nerve cells in the eye from death caused by lack of blood flow. In this project we will investigate how this remarkable effect is achieved.
Novel Mechanisms Of Early Age Related Macular Degeneration

Funding Amount
$933,953.00
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.
