About

Background

Ahalya is an optometrist and currently a senior lecturer at City University London which she joined in 2006. She has a specialist interest in visual impairment and runs the visual impairment clinic at City University London.

Ahalya studied at the Elite School of Optometry in Chennai India where she gained a first class degree in 1998. She subsequently worked at the Elite School of Optometry as a lecturer dividing her time between clinical work, teaching and doing research. In 2000 she came to the UK to take up a position as a research assistant at the University of Manchester and during this period completed a PhD in visual impairment under the guidance of Professor Christine Dickinson. She moved to Anglia Ruskin University in 2004 and worked as a research fellow investigating reaching in grasping in visually impaired people.

In early 2006 she passed the Non-EEA exams at first attempt and registered with the General Optical Council. Later that year she joined City University London where she has worked as a Lecturer and Programme Director for the undergraduate optometry course. She was promoted to a senior lecturer in 2010. Her main area of work has been on improving the quality of life of visually impaired people with particular emphasis on improving reading ability.

Research

Research overview

Ahalya's current research has concentrated on the following themes

- Improving reading ability in people who are visually impaired specifically people who suffer from Age Related Macular Degeneration (Eccentric Viewing) and have visual field loss due to stroke.  

- Improving the quality of low vision services for visually impaired people in the United Kingdom

- How colour vision is affected in people with Diabetic Mellitus with no retinopathy and different grades of retinopathy and how treatment may influence changes in colour vision

- Screening for visual impairment in children

Apart from the themes mentioned above her research over the past five years has looked at quality of life in visually impaired adults and children, reaching and grasping behaviour in visually impaired adults and repeatability of the MNREAD reading charts in visually impaired and normally sighted adults. She has also been involved in investigating how fixation disparity is used as a test of binocular vision in optometry clinics.
