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.
Ictal Characteristics Of Common Vestibular Diseases

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
The Effect Of Visual Impairment Arising From The Eye Diseases Glaucoma And Age-related Maculopathy On Driving Safety

Funding Amount
$645,591.00
Summary
Driving-related injuries are a serious public health problem for older people. Visual impairment is a significant risk factor for crashes. This prospective study will determine how the eye diseases glaucoma and age-related macular degeneration impact on driving safety. The outcomes will be used to develop a simple, reliable and practical battery of tests that can identify those at risk of crashes and to inform screening and intervention programs, patient education and driver licensing.
Mechanisms And Pathways Leading To Saccadic Suppression In Primate Brain

Funding Amount
$858,086.00
Summary
Only the central few degrees of the visual field are viewed in high resolution. Consequently, the eyes must be pointed at targets of interest using saccadic eye movements. Each saccade generates potentially disturbing image motion but this is never perceived: saccadic suppression. This project aims to characterise the neural basis of saccadic suppression using modern techniques. As a result, a prime question in Neuroscience for over 100 years can now be answered.

Summary
Benign Positioning Vertigo, the most common and correctable cause of dizziness, is caused by freely floating calcium carbonate crystals in the semicircular canals of the inner ear. Localizing the affected semicircular canal holds the key to effective treatment.A proportion of sufferers will not respond to conventional repositioning treatments due to incorrect diagnoses. This study will explore refractory BPV in detail, develop test methods that accurately localize the affected canal and devise t ....Benign Positioning Vertigo, the most common and correctable cause of dizziness, is caused by freely floating calcium carbonate crystals in the semicircular canals of the inner ear.

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.

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
$748,985.00
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.
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.
