Gordon Prescott - Senior Lecturer in Medical Statistics, University of Aberdeen

Ophthalmic statistics and research interests

My main sources of data are from diabetic retinopathy screening from Scotland and the UK. I contributed to the development and evaluation of an automated screening algorithm now used across Scotland. I have been co-applicant and statistician on a series of studies evaluating markers from manual and automated diabetic retinopathy screening in relation to health outcomes such as macular oedema, progression of diabetic retinopathy and stroke. I am also interested in other areas of health such as renal disease and in statistical methods for diagnostic testing and prognostic modelling.
