Nottingham University Hospitals NHS Trust
  Purpose
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.

Condition Intervention Phase
Amblyopia Device: I-BiTTM game Device: Non-I-BiTTM game Device: I-BiTTM DVD Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Evaluation and Development of a Novel Binocular Treatment (I-BiTTM) System Using Video Clips and Interactive Games to Improve Vision in Children With Amblyopia ('Lazy Eye').
