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.

Sharpening The Epidemiological Sword Against Ocular Trauma To Help Improve Management And Predict The Visual Outcomes, Contributing To The Development Of Prevention

Summary
Eye injury is the leading cause of monocular blindness internationally. Vision loss has devastating consequences, both financial and social. My research aims to develop a comprehensive international register for eye injury. Working with key international partners we will conduct a large-scale retrospective review to validate our data collection tool. Our aim is to revise outdated methods of scoring eye injury to better predict outcomes and improve management and treatment of eye injury.
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. 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-cranial pressure without the need for surgery.Read moreRead less
Facial paralysis results in loss of the ability to blink, which is the primary means of protecting and lubricating the eye. The eye becomes dry and ulcerated and eventually vision loss ensues. No therapy exists that can reliably restore blink and hence treatment is mostly palliative today. BLINC is an implantable device that artificially restores eye closure. It is wirelessly powered and readily implantable. BLINC has achieved eye closure similar to natural blinking in human cadaveric models.
An Evaluation Of How Well Brief Screening Instruments Can Classify Safe And Unsafe Older Drivers

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.
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.
Regulation Of Bone Marrow Progenitor Cells For Diabetic Retinopathy

Funding Amount
$442,930.00
Summary
Diabetic retinopathy (DR) is the leading cause of blindness in the working population of developed countries. Current treatments cannot restore the retinal vascular damage in DR. This project intends to combat DR by repairing the damaged retinal vasculature through short- and long-term regulations of the function of bone marrow derived endothelial progenitor cells. Success in this project would potentially have a major impact on all diabetic vascular complications.

Summary
The prosthesis developed by applicants, known also as Chirila keratoprosthesis, is an artificial implantable device designed to replace a diseased cornea or a failed corneal graft, and can be used in patients with no hope for a conventional replacement of the cornea with donor tissue. The device may ultimately find a wider application, as it has the potential to give better visual results than human donor grafts. Even when not rejected, the donor grafts may lead to problematic healing patterns a ....The prosthesis developed by applicants, known also as Chirila keratoprosthesis, is an artificial implantable device designed to replace a diseased cornea or a failed corneal graft, and can be used in patients with no hope for a conventional replacement of the cornea with donor tissue. The device may ultimately find a wider application, as it has the potential to give better visual results than human donor grafts. Even when not rejected, the donor grafts may lead to problematic healing patterns and astigmatism, both limiting the final vision of patients. From the 45 million blind people worldwide, at least 10 million are due to corneal diseases or trauma. The figures released by WHO suggest a doubling of this number by year 2020. Many countries are unable to provide sufficient donor corneas, sometimes for cultural-religious reasons. In developed countries, the replacement with donor tissue is a common procedure, but many patients remain untreated because their prognosis for successful grafting is poor. Figures released in Australia show that long-term success of donor transplantation is unlikely in the patients identified as high-risk recipients. Furthermore, even technically successful cases show disppointing final vision. The significance of the applicants' artificial cornea is that allows high-risk, or otherwise untreatable corneal blind patients, to have their vision restored, and it could ultimately reduce the need for donor corneal tissue. A phase I pilot study has been completed, and Phase II is currently underway with support from NH and MRC. These studies showed that the Chirila KPro is an effective means of reversible replacement of a diseased cornea.The proposed Phase III will evaluate both safety and effectiveness in different categories of patients in comparison with published outcomes of donor grafting, and will establish unequivocally the clinical potential of this prosthesis.Read moreRead less
THE ROLE OF MONOCYTIC LINEAGE CELLS IN MODELS OF CORNEAL DISEASE
Funder
National Health and Medical Research Council
Funding Amount
$311,567.00
Summary
Vision relies on sharp, focused undistorted images passing through the cornea, the clear 'window' at the front of the eye. Corneal disease causes over 5 million cases of blindness worldwide. In patients who damage the delicate covering of the cornea, due to trauma or contact lens wear, there is an increased risk of infection that may lead to blindness. This project will study the ways in which immune cells in the cornea detect invasion by potential pathogens.
