To evaluate the effect of using stereoscopic 3 D (S3D) technology visual training system in children with amblyopia.
30 children, 4-16 years old, 18 with ametropic amblyopia (AMA), and 12 with anisometropic amblyopia(ANA) were recruited in this study. A binocular 3D shutter glasses technology visual training system was used for training trials. Each training time lasted 1 hour, and the number of training trials totaled 33 (mean±SD=32±8) times on average, per-person. Before and after the training trials, we measured the best- corrected visual acuity (BCVA) of each eye, range of fusion by synoptophore, as well as near and distance stereopsis acuity by Yan Shaoming random-dot test and synoptophore respectively.
A significant difference was found pre- and post treatment in BCVA in both kinds of amblyopia studied. Significant improvement was also found in fusion range and stereopsis acuity. The improvement of fusion range and stereopsis recovery were higher in ANA than in AMA patients. The near stereopsis acuity recovered better than the stereo acuity in distance.
S3D display vision training systems are indicated for the recovery of stereoacuity in children with amblyopia.
