Patching or Gaming as Amblyopia Treatment?

Status Recruiting

Clinical Trial 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.

Clinical Trial Description

Amblyopia affects 3% of the children and is caused by strabismus, anisometropia or both. The 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. The rationale behind these games is by using dichoptic stimulation, with the contrast of the stimuli presented to the good eye reduced to match the appearance of the same stimuli when shown to the amblyopic eye, suppression can be alleviated. The many studies now conducted, demonstrate improvement in visual acuity with the games, the effect however is limited, but the rate of improvement is higher. In these studies, prescribed patching-time was compared to realised game-time. We have demonstrated in multiple studies that electronically measured compliance is low: on average only 50%. In this study we aim to compare the effect of patching therapy, using the ODM to objectively measure compliance, with the effect of a novel dichoptic action video game in children as well as in adults. In addition, the adult participants will undergo fMRI scans to document any changes in the visual cortex before and after either therapy. ;
