Optic Nerve Head Structure And Genetic/environmental Associations: A Population-based SD-OCT Study

Funding Amount

Summary
My research project combines two powerful new technologies, spectral domain-optical coherence tomography and the genome-wide association study, to investigate the physical and genetic characteristics of the optic nerve head in humans. Results from this work will help identify new glaucoma risk genes, increasing sensitivity and specificity for predicting glaucoma and expand our understanding of the disease mechanism allowing for the development of new treatments.
Non-invasive Retinal Vein Pulsation Pressure Measurement: A New Assessment Of Glaucoma Treatment.

Summary
Glaucoma is the second most common cause of blindness. It is a slowly degenerating disease and the level of treatment required is difficult to predict. At present there is no way of knowing whether the eye is receiving inadequate treatment. We have shown that retinal vein pulsation pressure measurements are an indicator of the likelihood of glaucoma progression. Our proposed studies hope to demonstrate for the first time that it is feasible to determine the appropriate treatment level for indivi ....Glaucoma is the second most common cause of blindness.

We have shown that retinal vein pulsation pressure measurements are an indicator of the likelihood of glaucoma progression.

Boosting Mitochondria- A New Approach For Protecting The Aging Optic Nerve In Glaucoma

Funding Amount

Summary
Increasing age is a major risk factor for neurodegeneration. We have recently shown that subjecting mice to intermittent periods of fasting improves mitochondrial function in the retina and reverses age-related decline in optic nerve vulnerability to injury. This project now aims to investigate key molecular pathway for restoring mitochondria and from this attempts to find more palatable therapeutic strategies for protecting the optic nerve from injury.
OXPHOS Upregulation To Preserve Vision In Leber's Hereditary Optic Neuropathy

Summary
Leber's Hereditary Optic Neuropathy (LHON) is a devastating blinding disease that preferentially affects young men. Sufferers have normal vision until teenage years or their twenties when a rapid loss of vision occurs that results in permanent blindness. It is caused by genetic changes in the mitochondrial DNA that we inherit from our mothers. The mitochondria are the cells' energy generators. We aim to use molecules similar to female hormones to boost energy as a new treatment to preserve visio ....Leber's Hereditary Optic Neuropathy (LHON) is a devastating blinding disease that preferentially affects young men.

The Neuro-ophthalmological Manifestations Of Human Mitochondrial Diseases.

Funding Amount
$100,675.00
Summary
Human mitochondrial diseases often result in neuro-ophthalmological abnormalities. We aim to examine a cohort of patients with mitochondrial disease and document the type and degree of neuro-ophthalmological abnormality. We will provide detail on the retina, optic nerve, oculomotor function, eyelids and visual acuity. We will examine the optic nerve in detail and perform optical coherence tomography and visual evoked potentials on each patient. We will compare results to age-matched controls.
Saving The Optic Nerve : Manipulating The Shp2-Caveolin Axis

Funding Amount

Summary
Glaucoma is a leading cause of blindness with many patients experiencing progressive vision loss despite treatment. We propose to use gene therapy techniques to manipulate the signalling pathway of Brain Derived Neurotrophic Factor and its receptor, along with biochemical and functional approaches to understand the mechanisms of glaucoma mediated eye damage and to develop new therapeutic strategies.
Energy Supply In Glaucoma: One Cell's Trash Is Another Cell's Treasure

Funding Amount
$122,712.00
Summary
Glaucoma is a leading cause of blindness and affects 65 million people worldwide, yet its underlying cause is not well understood. The work described in this research aims to understand the role of oligodendrocytes in provision of energy to retinal ganglion cell axons, and whether impaired energy supply in retinal ganglion cell axons and the optic nerve will lead to glaucoma. It is expected to provide new insight into glaucoma and potentially lead to new treatments.
