The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

A Novel Treatment For Ameliorating Retinal Vascular Disease
Funder

Funding Amount
$366,685.00
Summary
Retinal vascular disease is a leading cause of blindness and is currently treated by laser photocoagulation surgery. Although successful, this treatment is associated with serious side effects. Recently, Ellex Pty has developed a novel laser called the 2RT laser that is likely to be effective without the accompanying side effects. This study will allow examine the effect of the 2RT laser in animal models of retinal vascular disease so as to complete preclinical development of this laser.
Control Of Refractive Error Through Ionically Driven Fluid Movements

Summary
Myopia affects about half the world's population with recent studies suggesting epidemic proportions among some Asian schoolchildren though we are not seeing this in Australia. Costs associated with detection, monitoring and optical correction of low and high myopia are huge. High myopes (15% with > 6D) also have a greatly increased risk of blindness between the ages of 30 and 50 years due to secondary disorders associated with impaired fluid balance (retinal and choroidal oedema, macula oede ....Myopia affects about half the world's population with recent studies suggesting epidemic proportions among some Asian schoolchildren though we are not seeing this in Australia. Costs associated with detection, monitoring and optical correction of low and high myopia are huge. High myopes (15% with > 6D) also have a greatly increased risk of blindness between the ages of 30 and 50 years due to secondary disorders associated with impaired fluid balance (retinal and choroidal oedema, macula oedema, retinal detachment and glaucoma). Currently there is no accepted pharmaceutical treatment for myopia though our studies in chick have provided the theoretical rationale and experimental data for a potential therapy and patent. This patent is now at the PCT stage and attests that changes in the abundance of the ions of the subretinal space control fluid movements across the retina to choroid and can be modulated therapeutically by diuretics to control fluid flow and hence axial growth and myopia. This application aims to take our current knowledge about fluid control in myopic chick into a mammalian model prior to preclinical trials in monkey. We anticipate it will take 1 year to establish the feasibility of diuretic control of experimentally induced myopic refractive errors in guinea pigs and the best drug and best the dosage range. These studies will contribute to the scientific understanding and bring the proposed pharmaceutical therapy for myopia in adults and children to a point of full commercialization. We believe that the results found in chick will have significance for early and late-onset myopia in humans as it is highly likely that the same mechanisms of ocular growth regulation operate throughout life.Read moreRead less
Development Of New Anti-fibrotic Drugs For Prevention Of Diabetic Nephropathy.
Funder
National Health and Medical Research Council
Funding Amount
$133,800.00
Summary
Diabetic kidney disease is the leading cause of kidney failure in the developed world. Currently there is no treatment that reduces the excessive scarring that leads to kidney failure. This project aims to test whether a series of novel compounds that have been specifically designed to reduce scarring can prevent diabetic kidney disease.
Neuropathic Pain Drugs Based On The Endogenous Opioid Peptide Endomorphin 1.
Funder
National Health and Medical Research Council
Funding Amount
$209,470.00
Summary
We have developed a new pain drug based on the natural pain killing opioid peptide, Endomorhin 1. The new drug exhibits activity similar to morphine and gabapentin against neuropathic pain in animals but seems to act through a different mechanism. We will complete our preclinical investigation of this compound by assessing its side effect profile and tolerence inducing properties in animals. We will also continue our development of an orally active analogue of this important peptide.
