My research is looking at the blood vessels in the choroid - the layer at the back of the eye, behind the retina – and how these change throughout the disease process in Age-related Macular Degeneration (AMD). To view these vessels, I use a technique called Optical Coherence Tomography, or OCT. This technique takes scans through the back of the eye, which can be used to build 3-D images of the retina and choroid. It works in a similar way to ultrasound, but using long-wavelength light in place of sound. We are collaborating with a team of computer scientists at Swansea University (SwanseaVision) to analyse these images. Together, we are developing ways of automatically classifying OCT images collected from people with and without AMD, and with early- and late-stage AMD.

My main research interest is in Age-related Macular Degeneration (AMD), the current leading cause of vision loss in the UK. More specifically, I am looking at how blood vessels in the choroid (the layer beneath the retina) change throughout the disease process – in early, atrophic and neovascular AMD. I am using a technique called Optical Coherence Tomography (OCT) to view these vessels, which takes scans through the retina and choroid and can be used to build high resolution 3-D images of this area.
I am currently looking at the repeatability of the prototype long-wavelength OCT for detecting clinical signs, or “biomarkers”, of AMD in the choroid (e.g. changes to the vessel diameter and volume).
The aim of this research is to provide insight into the choroidal vessels changes in AMD and to identify potential clinical biomarkers for early disease detection and monitoring of disease progression in the future.
