Summary
Despite much research the precise pathoetiology of giant cell arteritis is poorly understood. Both environmental and genetic factors are thought to contribute to disease development. Though to date, no overriding mechanism for disease development has been identified. This research will apply modern molecular techniques to further explore the pathogenic processes in this devastating disease which in turn will hopefully provide insight into novel treatment modalities.
First-in-Field Study Of Mechanisms Operating In Post-Ebola Eye Disease

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.
This proposal seeks to develop a novel non-invasive method of measuring intra-cranial pressure, an important diagnostic parameter in many form of brain injury or neural disease. It works by quantitative video analysis of the pulsation of the major vein in the eye during induced rises in eye pressure. Many years of study by our group have determined the relationship between vein pulsation pressure and intra-cranial pressure, and this information is used to produce an accurate measurement of intra ....This proposal seeks to develop a novel non-invasive method of measuring intra-cranial pressure, an important diagnostic parameter in many form of brain injury or neural disease.

Age-related Macular Degeneration: A Cause And A Cure

Summary
Age-related macular degeneration (AMD) is a leading cause of vision loss and there is urgent need for an intervention to slow disease progression. AMD is characterised by debris accumulation in the retina and I will investigate if loss of function in cells that should clear this debris is a critical step in the development of AMD. I will trial a novel laser intervention to slow progression of disease and use basic science techniques to investigate the mechanisms of action of the laser.
Low Cost Smart Screening System For Sight Threatening Eye Disease: Diabetic Retinopathy

Summary
The aim of the project is to develop an automated disease grading and clinical decision support system for diabetic retinopathy (DR) to perform eye screening by primary care providers and nurses. The grading system will automatically extract DR pathology from a patient’s color fundus images by image processing, feature detection and machine learning algorithms. Based on the detected information, the system can classify the patient as non symptom or a specific disease level.
Most eye diseases have a genetic contribution, whether rare disorders affecting children such as retinoblastoma or congenital cataracts through to common disorders of older people such as myopia, age-related macular degeneration or glaucoma. We will continue our successful research to find genes that cause these diseases and use this to improve patient care and prevent blindness. We will work out how families can use this genetic information to participate in trials to develop new treatments.
Understanding Changes In Retinal Ganglion Cells Using A Glaucoma Model

Funding Amount

Summary
Glaucoma is a pressure related eye disease that is the second leading cause of blindness worldwide. The mechanisms by which glaucoma causes vision loss are poorly understood. At the Centre for Eye Research Australia, we aim to investigate changes within retinal ganglion cells – the neurons which carry light signal from the eye to the brain – using a glaucoma model. We hope to improve understanding of the disease process and highlight new therapeutic options for glaucoma.
A Genome-wide Association Scan To Identify Genetic Risk Factors For Sight Threatening Diabetic Retinopathy

Funding Amount

Summary
Diabetic eye disease is an important complication of diabetes that can lead to blindness. Very little is known about how diabetes causes eye disease, but genetics is known to play a role. We aim to identify genes that contribute to eye disease in diabetes patients. We will compare genes between patients with diabetes with and without severe diabetic eye disease using cutting edge genomic technology. We hope to be able to better predict risk of blindness and to move towards novel treatments.
Using Pharmacogenetics To Personalize Treatment Outcome To Ranibizumab (Lucentis) For The Eye Disease Age-related Macular Degeneration (AMD)

Funding Amount

Summary
The drug Lucentis has revolutionized the treatment of age-related macular degeneration, one of the commonest causes of severe vision loss in Australia. Unfortunately, up to 25% of patients continue to lose vision despite this treatment. We will use the latest gene chip technology to identify the genetic variant responsible for this poor response. Having this information will allow us to personalise treatment for the patient leading to improvement in their vision.
