No results posted yet for this study

Summary

Contrast balanced dichoptic videogame training has been found to improve sensory functions in adults with amblyopia; best corrected distance visual acuity (BCVA) and stereopsis, but its effect on motor function, namely amblyopic eye fixation stability, is unknown. Furthermore, the effect of treatment in cases of mild amblyopia is not well understood. The aim of this study is to find out the difference on fixation stability, BCVA and stereopsis in mild amblyopes after 6 weeks' contrast balanced dichoptic video game training.

Conditions

  • Amblyopia

Interventions

DEVICE

Dichoptic video game in an i-Pod touch device

Amblyope will wear a pair of red green goggles and play the video game with 'contrast-balanced' images displayed on the screen of an i-Pod touch device. The eye with weaker eyesight will see the image with high contrast, and the good eye will see the image with low contrast. The subject will play the game one hour per day for 6 weeks.

DEVICE

Video game in an i-Pod touch device

Amblyope will wear a pair of red green goggles and play the video game with equal contrast images displayed on the screen of an i-Pod touch device. Both eyes will see the image of same contrast. The subject will play the game one hour per day for 6 weeks.
