Glaucoma and AMD – through the eyes of the patient


Professor David Crabb, Professor of Statistics and Vision Research, City University London

Lecture synopsis

Successful clinical management of age related eye disease should equate to correct decisions about intensifying treatment, of initiating intervention, when patients are at risk of developing ‘visual disability’. Moreover, the benchmark for a new treatment success in a clinical trial should really be aligned to measureable changes that affect patient’s everyday life rather than imperceptible changes on a clinical chart.

Yet little is known about what visual loss, at different stages of glaucoma and age-related macular degeneration, specifically affect patients’ abilities to perform everyday visual tasks.

Being able to link the measurements taken in the clinic to at least an estimate of what patients visually ‘can’ and ‘cannot do’ would be enormously helpful. The first part of this presentation will showcase some of the work published in this area by our research laboratory in London illustrating, for example, the difficulties that patients have with reading, eye-hand coordination, driving, face recognition and searching for objects.

The second part of this talk will present results from a study highlighting the issue that ‘reconstructions’ of the visual symptoms of age-related eye disease, typically developed for patient information and disease awareness programs, very incorrectly imply that a patient’s perception of the world is through a black tunnel, or with vision obscured by black patches.

The talk will finally demonstrate how this information can be translated to design better patient education material for glaucoma.

About Professor David Crabb

Professor David Crabb David Crabb is Professor of Statistics and Vision Research at City, University of London. He gained degrees in Mathematics and Statistics at Oxford and Sheffield before completing a PhD in Visual Science in 1996. Following a post-doctoral position at University College London, and a lectureship in Nottingham, he returned to City in 2005 and was made professor in 2010.

Professor Crabb’s research laboratory (The Crabb Lab), contains a lively mixture of optometrists, vision scientists, ophthalmologists, psychologists, mathematicians and computer scientists. This research laboratory focuses on measurement in vision: visual fields, imaging and imaging processing, visual function, eye movements and electrophysiology.

The Crabb Lab also uses “big data” from NHS clinics to investigate health service delivery of age-related eye disease. Another main theme of his work is relating the different stages in age-related eye disease to patient’s vision related quality of life.

About Professor David Pickwell

David Pickwell was Professor of Optometry at the University of Bradford until his retirement in 1992. He was influential and highly respected in the UK and internationally.

He served the optometry profession and community in Yorkshire for over 40 years, and the University for over 25 years from its inception until his retirement. He laid the foundation for Bradford School of Optometry and Vision Science as we now know it.

This is the eigth annual lecture to recognise the contribution of Professor David Pickwell.
