Overview

Research overview

My main research interests are in basic and clinical psychophysics. Research in my lab is mainly aimed at gaining a better understanding of the functional architecture of the healthy visual system and how it is altered in neurodegenerative disorders such as glaucoma and macular degeneration. To address these aims, my lab uses a combination of psychophysics, electrophysiology, retinal imaging, and fMRI. We also us this understanding to inform the design of accurate and precise clinical tools for identifying the earliest deficits of visual perception in these disorders. I am Principal Investigator on the REVAMP Study, a UK-wide multi-site study funded by the Medical Research Council (MRC) Developmental Pathway Funding Scheme (DPFS), in which we are developing an evidence-based novel form of visual field test for identification and monitoring of eye disease, most notably glaucoma.

Teaching overview

I am module leader for 'Introduction to Clinical Optometric Practice' and also teach on the 'Normal Eye and Visual Pathway', 'Visual Correction', 'Advanced Visual Correction', and 'The Eye' modules. In addition, I supervise final year undergraduate students in the Research Project module.

Research

My main research interests are in basic and clinical psychophysics. Research in my lab is mainly aimed at gaining a better understanding of the functional architecture of the healthy visual system and how it is altered in neurodegenerative disorders such as glaucoma and macular degeneration. To address these aims, my lab uses a combination of psychophysics, electrophysiology, retinal imaging, and fMRI. We also us this understanding to inform the design of accurate and precise clinical tools for identifying the earliest deficits of visual perception in these disorders.

Better measures of the visual field in glaucoma

My research has focussed on characterising disease signal and response variability with various stimulus configurations in patients with glaucoma, and exploring ways in which the signal/noise ratio can be increased to improve the detection of subtle vision loss over time. I am also interested in how clinical measures of vision are affected by non-neural changes in the eye that occur with age or eye disease (e.g. increased intraocular straylight, crystalline lens yellowing).

Research & Evaluation of Area-Modulation Perimetry (REVAMP study)

My team has recently been awarded £1.82million by the MRC Developmental Pathway Funding Scheme (DPFS) for research into better ways to identify visual field loss in people with glaucoma. This work is being undertaken in collaboration with Dr Padraig Mulholland and Prof. Roger S Anderson at Ulster University, Prof. David F Garway-Heath at UCL Institute of Ophthalmology, and Prof. James E Morgan at Cardiff University. More details, including how to take part in the study, can be found on the REVAMP webpage.

Deficits of visual perception with age and disease

We have investigated changes in spatial summation with age and in early glaucoma. Two papers by our group, published side-by-side in Investigative Ophthalmology and Visual Science showed that although spatial summation is unchanged with advancing age, a loss of sensitivity (to a small spot of light varying in brightness) in early glaucoma can be accounted for by an enlargement of the area of complete spatial summation (Ricco's area). More recent work by our group has shown that temporal summation is also altered in glaucoma. Taken together, these findings have direct implications for the design of accurate clinical tests for measuring early visual field deficits in glaucoma.

Brain imaging

We use fMRI and psychophysics to study reorganisation in the human visual cortex in glaucoma, with colleagues in the Cardiff University Brain Research Imaging Centre (CUBRIC). This work is generously funded by Fight for Sight, the Eye Research Charity.

In vivo cone imaging

We have been undertaking a series of experiments in which cones are imaged in vivo using clinical instrumentation. Initial findings have recently been published in the journal Ophthalmology.

Visual acuity

Clinical visual acuity tests are quick and simple to perform, but the results can be highly variable, making them rather insensitive to subtle changes in vision that occur over time or in response to treatment. One contributing factor is the wide variation in optotype legibility. In one study, we showed how 'vanishing optotype acuity' (acuity measured with pseudo-high-pass optotypes) is more uniform across letters than acuity to conventional letters. Vanishing optotypes can be seen in Figure 3.
