Summary
The rapid rise in the prevalence of shortsightedness poses a major public health challenge. The Sydney Myopia Study has collected a large database on environmental risk factors, and has documented a major protective effect of children spending more time outdoors. Other studies suggest that myopia has a major genetic component. This study will collect DNA samples from over 4000 participants in the Sydney Myopia Study, and through genome-wide scanning, will look for gene-environment interactions.
Young Adult Myopia: Genetic And Environmental Associations

Summary
Myopia affects 80% of school leavers in the cities of East Asia, 45% of Asian Australian school leavers and is probably on the rise in European Australian adolescents. Increased levels of education and lack of time outdoors are known to increase the risk of myopia. We will examine 2,000 young adults to find the genes that interact with these risk factors. In addition to confirming when these risk factors are most important, identifying molecular pathways opens the avenue of new treatments.
The Clinical Impact Of Event-based Motion Correction In Paediatric PET-CT Brain Imaging

Summary
Movement of the head during PET-CT brain imaging can prevent accurate diagnosis by blurring and distorting the image. The problem is perhaps most acute in paediatric patients, many of whom must be anaesthetized or sedated to avoid motion. This work will establish whether a recently developed motion correction method can improve the clinical utility of PET-CT brain images in young patients, and reduce the need for sedation and anaesthesia during the PET scan.
