Prevalence, Ocular Biomarkers and Interventions for Myopia Progression in children
About the Project
Details of the Project
The rising global prevalence of myopia, expected to affect half the world’s population by 2050, represents a significant public health issue (1). Beyond a simple refractive error, myopia significantly increases the risk of sight threatening conditions including myopic macular degeneration, retinal detachment, glaucoma and cataract (2- 4). These findings underscore the critical need for evidence-based strategies to manage myopia, aiming to slow its progression and mitigate the risk of long-term ocular complications
Regional environmental and lifestyle factors strongly influence the onset and progression of myopia (5-7). Understanding how these factors shape refractive development is essential for improving prevention and management strategies.
This PhD project aims to evaluate the proportion of myopia in children attending an optometric practice by analysing longitudinal clinical data. Available information will include axial length measurements, refractive error status, OCT scans, and fundus images. Two age groups will be examined: 6–7 years and 12–14 years. These data will be compared with established cohort studies, such as the Aston Eye Study and the PreMO database (PreMO platform), to identify potential regional differences in refractive patterns and axial elongation.
A further objective is to identify ocular biomarkers associated with myopia and its progression. Key parameters will include axial length growth rate, choroidal thickness, retinal morphology, and structural changes observable on retinal imaging. Identifying these biomarkers may improve early detection of children at risk of fast progression.
The study will also evaluate the effectiveness of different myopia control interventions currently used in clinical practice, including specialised spectacle lenses and contact lenses.
Overall, this research will provide important insights into the prevalence, risk factors, and progression patterns of myopia in children. The findings will support earlier identification of high-risk children and help guide more effective, evidence-based intervention strategies.
