At-home treatment with dichoptic 3D movies significantly improves distance control in children with intermittent exotropia (IXT), while 2D movies do not show the same benefit, according to a study.
The study compared the effectiveness of dichoptic 3D and 2D movies in reducing suppression and enhancing stereoacuity.
Researchers enrolled 41 children (ages 3-13) with IXT, randomly assigning them to watch either 3D or 2D movies 3 times a week for 4 weeks. The primary outcome measured was the change in distance control score, assessed by pediatric eye specialists who were blinded to the treatment groups.
Children in the 3D group experienced a significant improvement in their distance control scores (1.38±1.06), while those in the 2D group had a less notable change (0.79±1.44). However, neither group showed significant changes in near control score, ocular alignment, or stereoacuity.
