About this trial

This is an interventional treatment trial for Amblyopia focused on measuring Amblyopia, I-BiT TM, Interactive games, Binocular

Eligibility Criteria

4 Years - 8 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion criteria:

  • Diagnosis of Anisometropic, Strabismic or Mixed Amblyopia as made by an Orthoptist
  • Male or Female
  • Aged 4 - 8 years inclusive.
  • Participant's parent or guardian is willing and able to give informed consent for participation in the study

Exclusion criteria:

  • Stimulus deprivation amblyopia.
  • Organic lesions of the eye preventing the establishment of good vision (e.g. media opacities, abnormalities in the fundus or optic nerve).
  • Lesions of the brain preventing the establishment of good vision (e.g. cortical visual impairment).
  • Patients diagnosed with Photosensitive Epilepsy
  • Patients diagnosed with or suspected of having Conjunctivitis
  • Loss of suppression at filter 4 or less as measured with the Sbisa Bar
  • Establishment of normal vision by refractive adaptation (wearing glasses after presentation).

5. Study Description

Brief Summary
The study aims to determine whether 30 minutes of treatment playing an interactive computer game weekly for 6 weeks, improves visual acuity. The game has been specially configured to ensure the amblyopic eye is preferentially stimulated and the patient wears shutter glasses which manipulate the image seen by each eye in order to provide more information to the amblyopic eye. Patients will be randomised to play the computer game using the I-BiTTM technology, play the computer game but without the I-BiTTM technology, or watch a DVD using the I-BiTTM technology.
