Chris Hammond is a Professor of Ophthalmology and a key member of the TwinsUK team. His research is focused on the genetics of common age-related eye diseases such as glaucoma, age-related cataract and myopia. He has shown that 77% of the variation in the need to wear glasses is due to genetic factors and he’s leading international efforts to identify genes causing short sight. Chris has over 70 publications including four book chapters and research articles in prestigious journals such as Nature and Nature Genetics. Current projects in Chris’s research group include investigations into rare variants of myopia and glaucoma, a diet and cataract study and a project on the cognitive, behavioural, environmental and genetic associations of myopia in young twins. Chris is also a practising ophthalmologist with a special interest in squint treatment and paediatric ophthalmology.
