Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this clinical study is to validate the effectiveness of the Vedea Amblyopia Therapy (VAT) as a treatment for children with lazy eye.

The main question it aims to answer is to prove that the VAT is as effective or more effective than the current gold standard for treating children with lazy eye. This is occlusion therapy by patching the dominant eye.

Participants will play VR-games specifically designed for children with lazy eye for 30 minutes per day, 5 days per week for 16 weeks. This group of children will be compared to children that undergo regular occlusion therapy to see how both treatments options compare.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vedea Amblyopia Therapy (VAT) then Vedea Amblyopia Therapy

Children in this intervention arm will use the VAT for 16 weeks.

After the initial 16 weeks of treatment these children will be allowed to use the VAT for another 16 weeks.

Group Type EXPERIMENTAL

Vedea Amblyopia Therapy (VAT)

Intervention Type DEVICE

Children will use the VAT for 5 days per week, 30 minutes per day. They play VR-games using a VR-headset, which content is optimized for dichoptic training.

Occlusion therapy then Vedea Amblyopia Therapy (VAT)

Children in this intervention arm will adhere to a 'care as usual' regimen consisting of occlusion therapy as prescribed by their health care provider. They will do so for 16 weeks.

After the initial 16 weeks of treatment these children will crossover into the experimental arm to examine if they are still responsive to the VAT after already completing 16 weeks of traditional treatment.

Group Type ACTIVE_COMPARATOR

Vedea Amblyopia Therapy (VAT)

Intervention Type DEVICE

Children will use the VAT for 5 days per week, 30 minutes per day. They play VR-games using a VR-headset, which content is optimized for dichoptic training.

Occlusion therapy

Intervention Type DEVICE

Children are given an eye patch to occlude their dominant eye with for a prescribed number of hours per day. This may typically range anywhere between 2-8 hours per day, depending on the severity of the amblyopia.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* wearing the full corrected refraction for ≥14 weeks to adapt to the glasses
* diagnosed with an unilateral anisometropic, strabismic and/or deprivation amblyopia.

Amblyopia was defined as an intraocular difference (IOD) in visual acuity (VA) of 0.2 log MAR (2 lines) or more. Angle of strabismus ≤ 10 prism diopters at near and distance fixation. Current clear media (in case of deprivation amblyopia after successful surgery).

* currently under treatment or starting treatment for unilateral amblyopia
* participants must have easy access to an Android device equal to or higher than a Samsung Galaxy S8
* written informed consent by parents or legal guardians

Exclusion Criteria

* current treatment with atropine penalisation
* documented history of severe negative side effects that occur with exposure to VR usage (eg. seizures or epileptic spasms)
* photosensitivity
* no developmental delay
* coexisting ocular pathology or systemic diseases
