Mr Danny Mitry, our Ophthalmology Clinical Lead, is working on some fascinating and important projects with the UK Biobank. In one of these, they are recruiting untrained individuals to analyse vast quantities of clinical eye images, allowing them to collect a wealth of data based on rapid analysis of pattern-recognition tasks that would otherwise be very laborious. The technique, known as ‘crowdsourcing’, was interestingly pioneered in the development of the Oxford English Dictionary, genealogy, and other branches of science, including astronomy! Now, the UK Biobank will be putting the method to use for the benefit of human health.
