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.
Novel Ophthalmic Topical Formulation Targeting Molecular Pathogenesis Of Corneal Haze

Funding Amount
$296,090.00
Summary
Presently, no drugs are proven to cure corneal haze/scarring, major leading cause of global blindness. Haze is caused by eye trauma, infections or refractive laser surgeries. We aim to test a non toxic, novel ophthalmic topical formulation developed to act on molecular and cellular targets of haze formation. The successful completion of the study will determine formulation’s optimal dose, safety and efficacy for its future potential clinical use in reversing corneal scarring/haze without side ef ....Presently, no drugs are proven to cure corneal haze/scarring, major leading cause of global blindness.

Toxoplasma Gondii Infection Of Human Retinal Pigment Epithelium

Funding Amount
$460,668.00
Summary
Ocular toxoplasmosis is a vision-threatening parasitic eye infection that is common in Australia and worldwide. No treatment cures the disease. This work will characterize cellular and molecular events occuring in the eye during an infection, which is an important first step toward the development of more effective treatments for patients with the condition.
The Role Of Microglia In Regulating Photoreceptor Integrity
Funder
National Health and Medical Research Council
Funding Amount
$556,405.00
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.
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.
Inhibition Of Specific NOX Isoforms As A New Treatment For Hypertensive And Diabetic Retinopathy

Funding Amount
$855,172.00
Summary
Almost all people with diabetes will develop some retinal disease (diabetic retinopathy, DR) and vision loss. Unfortunately, current treatments target the late stages of DR, do not prevent disease progression and can be damaging. This project will uncover the role of a fundamental process that occurs in DR, called oxidative stress. We will evaluate a major cause of oxidative stress called NOX, which exists in various forms. Animal models of diabetes in which NOXes have been manipulated as well a
Targeting Neuroserpin-plasmin Interactions To Protect The Retina In Glaucoma

Funding Amount
$648,965.00
Summary
Glaucoma causes blindness and despite our best treatment many patients continue to progress. A new approach is needed to protect the cells that die in the retina. We have established that a common protease – plasmin – is involved in the process, and a protein that normally regulates it – neuroserpin – is downregulated in the disease. We aim to modify neuroserpin using an ocular gene therapy approach and show it could be used as a novel therapy in glaucoma.
Clinical Trial Of A Suprachoroidal Visual Prosthesis For The Profoundly Vision Impaired

Funding Amount
$1,098,802.00
Summary
For 15 years we have been designing a bionic eye. We have made a device called the Phoenix99 and shown in short term animal tests that it is both safe to implant but also that it potentially performs better than any other device in the world. We are requesting funds to complete longer term animal testing of the device and then commence a small human clinical trial to demonstrate the benefits of the technology – specifically that it is able to help blind people navigate without assistance.
Seeing Clearly: Examining The Consequences Of Glaucoma For The Human Brain
Funder
National Health and Medical Research Council
Funding Amount
$439,694.00
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.
Young Adult Myopia: Genetic And Environmental Associations

Funding Amount
$809,271.00
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.
