Optic Nerve & Orbit Studies
Objective
The primary objective of our optic nerve and orbits studies is to identify which structures exhibit greater or lesser deformability in response to pressure differences, and to explore how this differs in the presence of certain diseases. By gaining a deeper understanding of these mechanisms, we aim to improve our knowledge of ocular conditions and contribute to the development of more effective treatments.
Our studies mark the first-ever amplified MRI investigation of the orbit. By examining the subtle movements within the orbit that occur with each heartbeat, we can uncover invaluable insights into the dynamics of this complex region.
Project One: Goggles Intervention Project
Team lead: Dr Jesse Gale
Funded by Vision Research Foundation and Rapanui Trust
In this unique study, we employ customised goggles that have the ability to apply both positive and negative pressures. This innovative approach sets our research apart and allows us to investigate the response of various structures to different pressure conditions.
We are excited about the potential of this research to shed light on the compliance and deformability of ocular structures and their implications for various diseases. As our project progresses, we will continue to update this webpage with significant findings and advancements. Join us on this groundbreaking journey as we strive to unravel the mysteries of the eye and pave the way for improved diagnostics and treatments in ophthalmology.
Project Two: Balancing act: understanding roles of interocular and intracranial pressures in the eye
Team lead: Professor Helen Danesh-Meyer
Funded by Vision Research Foundation
There is a need for better biomarkers for predicting disease progression in diseases such as glaucoma, idiopathic intracranial hypertension and papellidema. For example, glaucoma is a serious ocular condition characterised by progressive damage to the optic nerve, often resulting in vision loss and even blindness. Early detection and timely intervention are crucial for preventing irreversible damage. One of the challenges in managing glaucoma effectively is the lack of reliable biomarkers that can accurately predict disease progression. Glaucoma poses a significant public health concern, affecting millions of individuals worldwide.
Developing better biomarkers for glaucoma is imperative for enhancing our ability to diagnose the disease early, monitor its progression, and tailor treatments to individual patients.
We wish to investigate the role of structure and dynamics in the eye across an interesting membrane called laminar cribosa using advanced imaging. Our research aims to contribute to the advancement of glaucoma management by identifying novel biomarkers that could revolutionise the way we approach these diseases. Join us in our mission to improve the lives of those at risk and pave the way for more targeted and effective therapies.
