Anna Horwood is a professor of orthoptics and visual development at the University of Reading. She trained as an orthoptist and now combines research with clinical orthoptics. A survey of the visual behaviour of orthoptists’ infants spawned a series of studies into the development of binocular vision led to a PhD in 2002. Anna has had a long-standing collaboration with Patricia Riddell at the University of Reading since 1997, helping set up, and now running the Infant Vision Laboratory. She was awarded the International Orthoptic Association Research Award in 2008 and the Bielschowsky Lecture from the International Strabismological Association in 2018. She is the research and innovation director of the British and Irish Orthoptic Society, associate editor of the British and Irish Orthoptic Journal and an executive committee member of the British Isles Paediatric Ophthalmology and Strabismus Association. She has given many major keynote lectures around the world, and is involved in clinical teaching and examining of orthoptists. She is a NIHR senior research mentor and a teaching volunteer for ORBIS and the International Orthoptic Association.
