(3-5 years)		 Download

Why should my child have a Vision Screening Test? The aim of the Vision Screening Test early detection and referral of children with abnormal vision, which may be due to: 1) amblyopia
2) conditions that may cause amblyopia What is
An amblyopic eye is an eye with poor vision. * Amblyopic usually (but not always) occurs in only one eye. * Amblyopic can be caused by:
A refractive error, i.e. short-sightedness, long-sightedness, astigmatism (e.g. severe long-sightedness may cause amblyopia in a young child); A big difference in refractive error between the two eyes (e.g. one eye with normal vision and the other with a significant refractive error); A squint; or Opacities in the refractive media (e.g. cataract).
*As a result, the brain fails to perceive a clear image from the affected eye. The poor vision in an amblyopic eye is therefore not correctable by spectacles alone. * Treatment is more effective before the age of 8 to 9 years. If untreated, poor vision will become permanent. * Amblyopia may be a barrier to certain careers and may leave the individual with very poor vision if there is loss of vision in the good eye through disease or trauma.
