Reason for Study
In recent years, a new type of treatment for amblyopia has been tried called dichoptic training. This is still being studied to see how effective it is to treat lazy eye conditions. Dichoptic training involves giving visual information to both the lazy eye and non-lazy eye simultaneously, but differently to try to get the lazy eye to work better. If effective, this may be used as an alternative to traditional therapy, such as patching.
Why is this important
Amblyopia is one of the most common causes of vision loss in the United States and elsewhere. Current treatment with patching or eye drops is often poorly tolerated by children and therefore not done.
Who is eligible
The current study is for children ages 4-12 with one lazy eye with vision between 20/40 and 20/200. This may be due to strabismus (eyes not staying straight) or anisometropia (eyes focusing differently). These are the 2 most common causes of amblyopia.
Will my child benefit
There may be an improvement in amblyopia during the study. The study is to determine the safety and effectiveness of this treatment. Your child will not be doing other amblyopia treatment during the 4-month course of this study
How long is the study and what is involved
The study will last for 16 weeks. There will be 7 visits during the study period. This will include 3 visits normally done to follow someone with amblyopia and billed to insurance. There is no charge for the four additional visits done as part of the study.
Your child will be asked to view a movie of their choice from a library of movies on a VR headset for 1 hour 6 days a week. Each eye will receive different parts of the movie image at different contrast levels based on the child’s amblyopia. The VR headset will be loaned for the duration of the study.
There is compensation for participation in the form of gift cards of $20.00 for each visit, or $140.00 for the seven study visits
