Keziah’s principal teaching, research and clinical interests are in low vision. She runs the low vision clinic within the University Eye Clinic, and teaches the topic to optometry and dispensing optics students. Keziah was the 2017 recipient of the Neil Charman medal for excellence in optometric research from the College of Optometrists for her research work in low vision.

Keziah also specialises in ophthalmic lenses and dispensing, and is an author of an undergraduate text book on this subject (CW Fowler & K Latham Petre. Spectacle Lenses: Theory & Practice. Butterworth-Heinemann, 2001). She has a clinical interest in glaucoma, and is an OSI (Optometrist with Special Interest) in glaucoma within Hinchingbrooke Hospital's CHANGES scheme. Keziah was previously Faculty lead for Athena SWAN.

Appointments for the Low Vision Clinic can be made by contacting the University Eye Clinic on 01223 698070.

Research interests

  • The assessment of function and optimization of rehabilitation for people with visual impairment. 'Assessment of function' covers a range of areas including the most effective ways to assess clinical visual function, objective assessment of activities of daily living (including reading tasks and movement analysis), and the development and use of patient reported outcome measures (including the use of Rasch analysis) for the assessment of visual difficulties and of quality of life
  • More generally, research interests are in the visual function of other groups such as people with autism spectrum conditions (ASC), drivers, and peripheral vision
  • Keziah is a member of our Visual Function and Physiology Research Group
