This opportunity is now closed.
Subject: Biomedical Sciences
The WHO has identified childhood obesity, resulting from imbalance between diet and exercise, as a serious 21st Century public health challenge. Concurrently, modern children’s lifestyles are promoting an unprecedented rise in short-sight (myopia) across the world. Ulster’s Northern Ireland Childhood Errors of Refraction (NICER) study has demonstrated that prevalence amongst UK teenagers has more than doubled in the last 50 years and is appearing in children at younger ages. This is alarming because myopia is strongly linked with sight-threatening diseases such as glaucoma and maculopathy, and the younger myopia occurs, the larger the magnitude of myopia that will subsequently develop and the greater the likelihood of future vision impairment. Rising levels of myopia will impose increasing costs on both the individual and healthcare services in the UK unless strategies are introduced to reduce the number of children becoming myopic.
However, before such strategies can be developed a better understanding is needed of the factors which promote the excessive eye growth characterising myopia. An individual’s risk for myopia is influenced by genetic factors (ethnicity, parental history of myopia). Eye shape in early childhood may also influence onset/progression of myopia. These myopigenic features are not amenable to modification. However, recent studies have identified environmental/lifestyle factors which influence myopia, including protective factors (spending time outdoors) and factors that increase risk for myopia (sedentary lifestyles, increased time spent reading).
To-date, these modifiable risk factors have primarily been assessed using self-report, rather than objective measurement. Robust quantitative data describing the inter-relationship between myopia, time spent outdoors, physical activity, reading, and other near vision activities (e.g. tablet/smartphone use) are not available for UK/Irish children. We will use a cross-sectional design based on the NICER sampling framework to identify myopic/non-myopic children (12-13yrs) and younger children (6-7yrs) at high/low risk of future myopia. Refractive error, eye shape and genetic factors will be recorded. Modern ‘wearable’ devices will be used to objectively quantify participants’ exposure to outdoor light, physical activity (both using Phillips Actigraph) and near vision activities (using Clouclip). These measures will allow us to establish robust UK-specific data on which to base anti-myopia strategies and public health advice. Such strategies/advice may ultimately benefit both eye and physical health.
This project involves strategic collaboration between Ulster University’s Optometry and Vision Science Research Group and the Sports Science Research Institute, who have extensive expertise in quantification of activity. Applicants should be optometrists registered with the General Optical Council, or able to register with the General Optical Council within six months of commencing the project. They need access to a car and a full UK driving license.
