Project Summary
The incidence of myopia amongst children and young adults in westernised economies will reach "epidemic" levels by 2050, increasing five-fold globally. While there are no statistics yet available for New Zealand, the factors driving this global epidemic exist here and it is very likely that NZ will follow this trend. The early onset and rapid progression of myopia in children can have severe consequences for vision and the long-term well-being of the affected individual. High order levels of myopia (≥8 dioptres) are associated with deleterious structural changes to the eye which increase the risk of significant visual loss and blindness in later life by up to 10 fold. Robust clinical data demonstrate that many of these issues can be prevented if myopia is detected early and, timely myopia control interventions are instigated. For example, a myopia of 2 Diopters at the age of 6 will often progress to 8 Diopters of myopia by age 17. However, if detected and corrected, the same eye will only be at 4 Diopters at the same age. High levels of myopia are long been associated with the onset of Staphyloma in children, and non-reversible blindness.
