Project Summary
f eye problems such as unequal refractive error (anisometropia) or strabismus (squint) occur in early childhood they can affect the development of brain areas that are responsible for sight and cause a life-time lasting condition called amblyopia. Amblyopia almost doubles the lifetime risk of legal blindness, affects motor development and impairs reading. Amblyopia is characterized by a range of vision deficits including a loss of visual acuity (VA), typically in one eye, and impaired binocular (3D) vision[2]. With a prevalence of 1.3-3.6%, amblyopia is the leading worldwide cause of unilateral visual impairment in people below the age of 80 and affects approximately 150,000 people in New Zealand alone. Moreover it disproportionally affects people from lower socio-economic groups and also has significant economic implications. For example, untreated amblyopia is associated with a US$7.4 billion loss of GDP in the USA, which equates to a loss of approximately $110 million NZD.
