VT-IXT Trial Summary

This trial is testing whether vision therapy can help control a type of eye misalignment. The results will help determine whether to do a longer trial testing the therapy.

Who is the study for?
This trial is for kids aged 8-16 with a specific eye alignment issue called intermittent exotropia, where one eye occasionally drifts outward. They should have certain levels of control over their eye movement and good depth perception. Kids who plan to move soon or can't commit to the study's process are not eligible.Check my eligibility
What is being tested?
The study tests if vision therapy can help manage intermittent exotropia better than just watching the condition without treatment. Participants will be randomly assigned to either receive vision therapy or be observed, helping decide if more extensive research is needed.See study design
