Choroid and myopia
Research suggests that the choroid plays a major role in guiding axial eye growth. Using high resolution optical coherence tomography, this project investigates choroidal responses to imposed optical defocus and atropine eye drops in health and disease. For more...
Atropine for myopia control
This project investigates the mechanisms underlying atropine control of eye growth and myopia. Nightly instillation of atropine is the most successful treatment for inhibiting myopia progression at present. However, the site and mode of atropine’s actions are yet to...
Myopia control – blue light, intensity, and experimental myopia
Blue (short-wavelength) LED light suppresses the development of experimental myopia in the chick at apparently lower intensity levels than white LED light. This may be due to either the eye’s chromatic aberration focussing blue light in front of the retina, or through...
A device for the measurement of visual function for use with young children
The earlier a vision problem is detected, the greater the benefit to be derived from a treatment intervention. However, there are currently no reliable, objective and clinically usable tests available today, that allow for the measurement and detection of vision...
‘The Auckland Optotypes’ displayed on a tablet computer work well to identify children with vision loss
In NZ we have an excellent ‘before school’ screening program. Screening includes a test of the finest detail a child can see (visual acuity). Ideally, the test would be able to separate children with good vision from those who should see an eye doctor. We compared a...
The effect of virtual reality headsets on the eyes
Virtual reality (VR) is becoming mainstream, but we do not know the effects of VR on the body – or the eyes. VR headsets display stereoscopic images on a screen which is just centimetres from the eyes, which is then viewed through high powered spectacle lenses. We...
The virtual eye
Currently, there is no platform which integrates results from different tests of an eye exam with one another. This often poses difficulties in diagnosis, lengthens clinical visit time, and adds to the healthcare cost. This project focuses on processing data obtained...
The computational fluid dynamics model of the in-vivo human lens
The human lens is a major optical component that contributes to overall vision. Fluid dynamics and physiology of the lens change as we age, which leads to the formation of diseases such as cataract. In this project, I have focused on creating aging human lens computer...
Studying the effects of ageing on intravitreal drug administration using bi-modal modelling approach
Age-related macular degeneration (AMD) is the leading cause of blindness in New Zealand, affecting 184,000 people in 2014, costing $391.1 million in 2016, or $19,825 per patient. Anti-VEGF injection is the most effective way to control AMD progression, which is...
