Myopia is the leading cause of distance refractive error, with estimates of 50% of the global population being affected by 2050. Our myopia research is a collaboration between research groups at ARU and partners globally.
We investigated factors related to the accommodation system both cross-sectionally and longitudinally in myopes. Our researchers identified reasons for such deficits in accommodation and were the first to show that reduced accommodative response in myopes may be due to a decrease in sensitivity to negative lens blur, and that the optimum focus for a system which drives accommodation is more negative in myopes.
We investigated potential treatments for myopia, mainly vision training and specially designed contact lenses to improve the accuracy of accommodation during near-work. Preliminary data indicated that the treatment was successful in improving the accommodative responses of myopes. We were the first to show to show that accommodative facility and lag of accommodation are independently associated with the progression of myopia in young adults.
We have contributed to the debate on the contribution of peripheral refractive error to myopia progression by demonstrating how these errors vary in the nasal and temporal retina in distance and near vision.
Our study in India examined the interaction between family history of myopia and amount of near-work, showing that myopes with a family history of myopia progress more than those without, and also highlighting association between myopia and IQ scores.
We are conducting a number of clinical trials on myopia and progression of myopia.
Support for this research has come from the Government of Australia and the Brien Holden Institute.
