Interactive binocular treatment (I-BiT) for amblyopia: results of a pilot study of 3D shutter glasses system.
.....A computer-based interactive binocular treatment system (I-BiT) for amblyopia has been developed, which utilizes commercially available 3D 'shutter glasses'. ....Thirty minutes of I-BiT treatment was given once weekly for 6 weeks. Treatment sessions consisted of playing a computer game and watching a DVD through the I-BiT system. VA was assessed at baseline, mid-treatment, at the end of treatment, and at 4 weeks post treatment. ..... Nine patients (90%) completed the full course of I-BiT treatment with a mean improvement of 0.18 .... Six out of nine patients (67%) who completed the treatment showed a clinically significant improvement....This small, uncontrolled study has shown VA gains with 3 hours of I-BiT treatment. ...-these results suggest that further investigation of I-BiT treatment is worthwhile......
Comments: I always find it amazing when my colleagues re-invent the vision therapy paradigm that amblyopia is a binocular vision problem that should be treated in a binocular fashion. Amazed and over-joyed. Now if they would only credit the pioneers of behavioral/functional/developmental optometry for these insights I would be also be pleased. DM
