Brief Summary
Amblyopia affects 3% of the children and is caused by strabismus, anisometropia or both. Standard treatment is glasses and patching therapy. From North-America, behavioural training, i.e. dichoptic training, perceptual learning and video gaming, has become increasingly popular to improve visual acuity not only in children but also in adults. In this study we aim to compare the standard occlusion therapy with dichoptic video gaming.

Outcome Measures
Primary Outcomes (1)
Visual Acuity improvement
Visual Acuity improvement (logMAR units/time period) in children with amblyopia treated with patching therapy vs dichoptic video gaming
24 weeks
Study Arms (2)
Occlusion therapy
ACTIVE COMPARATORParticipants are prescribed 2 hours of occlusion therapy per day, 7 days a week.
Dichoptic video game therapy
EXPERIMENTALParticipants receive dichoptic video game therapy: 1 hour per week at the out-patient clinic under direct supervision.
Interventions
Dichoptic video gaming for 1 hour per week, viewed through the Oculus Rift.
Eligibility Criteria
You may qualify if:
- Amblyopia; an interocular difference in visual acuity of at least 2 logMAR lines.
You may not qualify if:
- A non-comitant or large angle constant strabismus \>30Prism Dioptres, a neurological disorder, nystagmus, other eye disorders and diminished acuity due to medication, brain damage or trauma.
