REMOVING THE BRAKES ON BRAIN PLASTICITY IN ADULTS WITH AMBLYOPIA
Experience-dependent
plasticity is closely linked with the development of sensory function.
Beyond this sensitive period, developmental plasticity is actively
limited; however, new studies provide growing evidence for plasticity in
the adult visual system. The amblyopic visual system is an excellent
model for examining the “brakes” that limit recovery of function beyond
the critical period. While amblyopia can often be reversed when treated
early, conventional treatment is generally not undertaken in older
children and adults. However new clinical and experimental studies in
both animals and humans provide evidence for neural plasticity beyond
the critical period. The results suggest that perceptual learning and
video game play may be effective in improving a range of visual
performance measures and importantly the improvements may transfer to
better visual acuity and stereopsis. These findings, along with the
results of new clinical trials, suggest that it might be time to
re-consider our notions about neural plasticity in amblyopia.
