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.

Summary
Cataract, the loss of transparency of the eye lens, is a major cause of blindness. We have identified molecules in the lens important for maintenance of its transparency and plan to characterise their effectiveness in preventing cataract formation.
Toxoplasma Gondii Infection Of Human Retinal Pigment Epithelium

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.
First-in-Field Study Of Mechanisms Operating In Post-Ebola Eye Disease

Funding Amount

Summary
Ebola virus disease is a life-threatening illness with no treatment. Survivors of the disease are at risk of uveitis - inflammation inside the eye - related to the ability of Ebola virus to persist in the eye. Our research will examine the cellular and molecular events that occur in an eye that harbours Ebola virus. This work will be an important step towards the development of treatments for uveitis caused by Ebola virus.
Most diseases are much more common in the elderly. The reasons are poorly understood. We have evidence that the most common eye diseases, cataract and presbyopia, are due to the fact that the large molecules that make up the lens do not turnover. In lenses of older people proteins, which make up the bulk of the transparent tissue, become degraded. It turns out that very long lived proteins are quite common in the body. This proposal seeks to determine what role degradation of these ancient prote ....Most diseases are much more common in the elderly. The reasons are poorly understood.

Strabismus is the pathological misalignment of the eyes associated with loss of binocular vision and is one of the most common human ophthalmological disorders. Patients with comitant strabismus have full eye movements, whereas patients with incomitant strabismus have limited eye movements, which causes the angle of strabismus to vary with gaze direction. This project aims to define genetic contributors to comitant congenital strabismus.
Eye Movements And The Neural Representation Of Visual Space

Funding Amount
$459,061.00
Summary
This project will investigate the brain mechanisms that underlie our ability to perceive the locations of objects using vision. This fundamental ability supports a range of important functions including visually-guided reaching, navigation during walking, and spatial awareness, but remains poorly understood. Using physiological, behavioural, and analytical methods, this project will fill a key knowledge gap in visual neuroscience and form a basis for a range of clinical and biomedical advances.

Summary
vertigo is a disabling symptom affecting 1 million Australians at any given time. Acute vertigo is associated with abnormal eye movements or nystagmus, the pattern of which points to its origin. In this project, we extract the unique characteristics of distinct vertigo syndromes to enable their separation
Neuro-feedback For Improved Efficacy Of Retinal Prostheses

Funding Amount
$653,655.00
Summary
Bionic eyes offer the possibility to return sight to the blind. Existing retinal implants are effective at delivering basic visual percepts, namely brief spots of light. Our team is now working on building the second generation of bionic eyes that include the ability to both stimulate the visual system (the retina) and record its response. By recording the evoked responses, we can adjust and optimize the stimulation to restore a persistent high spatial resolution sense of vision to the blind.
An Evaluation Of How Well Brief Screening Instruments Can Classify Safe And Unsafe Older Drivers
Funder
National Health and Medical Research Council
Funding Amount
$877,030.00
Summary
This proposal seeks to evaluate a screening instrument that will assess the safety of older drivers. The assessment takes less than 10 minutes and involves measuring aspects of vision, reaction time, and balance. We will assess this instrument in persons who are potentially at risk of being unsafe drivers due to visual, cognitive or medical problems. The instrument will be evaluated against the results of an on-road driving assessment and compared to other methods of evaluating older drivers.
