Research Interests

My primary research interest is macular disease, the number one cause of visual impairment in the UK. By developing new technologies capable of detecting and monitoring early age-related macular degeneration, I hope we can speed up the development of therapeutic interventions. The techniques developed in our lab are currently being used to obtain proof of concept data in early stage clinical trials. However, whilst finding a cure for macular disease is my dream, I also recognise that people who already have this condition have to cope with visual impairment and therefore I am also interested in the development of high quality rehabilitation services.

Teaching Overview

As a clinician I am passionate about clinical teaching quality. I teach our 2nd year undergraduates how to undertake an eye examination in a module called clinical studies and dispensing (OP 2101). I also teach Optometric Practice in the 3rd year and work in our Primary Care Clinics. More recently, I have taken on the role of module leader for the research module in our MSc programme.

Research Topics and Related Projects

The primary focus of my research is macular disease. Accounting for 57% of all visual impairment in the UK, macular disease is responsible for significant individual suffering and places a heavy burden on society.

My research revolves around two distinct areas of activity. The first is concerned with the development of biomarkers for macular disease that can be used to expedite the evaluation of novel therapeutic interventions. The second relates to the identification of effective rehabilitation interventions that can help people with advanced macular disease cope with vision loss.

Results from our lab indicated that dark adaptation, the recovery of visual function in the dark following a period of light adaptation, is a sensitive candidate biomarker for AMD. Hence we have spent the last few years refining the test protocol i.e. examining the effect of stimulus location, bleach intensity and psychophysical methods on sensitivity and specificity.

Rehabilitation research is my other passion. How can we help people with untreatable visual loss maintain their independence? My involvement in the establishment of the community based Welsh Low Vision Service was a great opportunity to evaluate a range of interventions and survey based outcome measures. The Low Vision Service Model Evaluation (LOVSME) project, supported by the RNIB, was another collaborative project examining the effectiveness of low vision services. And more recently, a group of us have begun to examine the impact of mental health status on rehabilitation outcomes. The Depression in Visual Impairment Trial (DEPVIT), funded by Guide Dogs, is evaluating 3 treatments for depression in a multicentre RCT. We hope the results will help shape future NICE guidance.
