Professor Garway-Heath’s research has yielded many new diagnostic and monitoring tools, including the Moorfields Motion Displacement Test that identifies the loss of peripheral vision; The Moorfields Regression Analysis, software that assists glaucoma diagnosis from scanning laser tomography images; and the Garway-Heath Map, which is used in research and clinical practice to map the correspondence between visual field and optic nerve head damage. He was chief investigator for the UK Glaucoma Treatment Study, the first placebo-controlled trial for the medical treatment of glaucoma with a visual field loss outcome. In his research, he aims to continue to improve glaucoma diagnostic techniques, clinical trial design and identify risk factors for glaucoma. He recognizes the importance of multidisciplinary collaboration for successful research and has long-term productive collaborations with statisticians, computer scientists and academics in other fields of medicine. Advancement of knowledge and scientific progress comes from bias-free dialogue with peers, mentees and mentors.
