About

Background

John joined City University London in 2004, he is Professor of Clinical Visual Science Following a first degree in biochemistry at Cardiff University, John studied optometry at Aston University, graduating with a first class honours degree. After a pre-registration year at Moorfields Eye Hospital in London he undertook postgraduate research at City University London, receiving his PhD in 1992. He then completed a post-doctoral research fellowship in Neuroscience at University College London. He subsequently returned to join the academic staff at City University where he currently holds a Chair in Clinical Visual Science. John has a strong interest in evidence-based practice and has recently completed a Masters degree in Evidence-based Healthcare at the University of Oxford.

Research

Research overview

Although eye disease can affect any age group, the primary interests of John's research group are in chronic eye diseases in the elderly, particularly glaucoma and age-related macular degeneration (AMD). The research covers disease prevention, improved methods for detection, with a particular emphasis on the evaluation of models of eye care service delivery. John is an experienced systematic reviewer and has completed several reviews for the Cochrane Eyes and Vision Group on nutritional interventions in AMD.

Research areas

- Models of ophthalmic service delivery
- Detection of age-related eye disease in primary care
- Nutrition and eye disease
- Systematic reviews in eyes and vision
