Professor Anna Horwood
Areas of interest
Anna Horwood researches ocular focusing (accommodation and convergence) in many different groups of participants: infants, typical adults and children, and hospital patients with eye movement disorders.
The unique Infant Vision Laboratory has produced new insights into how the eyes respond to images moving in depth – a process fundamental to maintaining binocular vision and preventing many common eye problems.
Funding from the Medical Research Council, the National Institute for Health Research and Fight for Sight has supported work which is helping clinical ophthalmologists, orthoptists, optometrists and vision scientists around the world to improve children's eyecare.
