依赖经验的可塑性的关键时期无处不在。依赖经验的可塑性与感觉功能的发展密切相关的观点仍然被广泛接受；然而，也有越来越多的证据表明成人神经系统的可塑性。本文根据神经可塑性的最新实验和临床证据，对弱视治疗的关键期的概念进行了综述。具体地说，患有弱视的成年人可以通过在具有挑战性的视觉任务中进行广泛的练习来提高他们的知觉表现，这种改善可能会转化为视觉敏锐度的提高。据推测，这些相同的机制至少解释了弱视治疗中出现的部分改善。(C)2005年威利期刊公司。
Critical periods for experience-dependent plasticity are ubiquitous. The idea that experience-dependent plasticity is closely linked with the development of sensory function is still widely held; however, there also is growing evidence for plasticity in the adult nervous system. This article reviews the notion of a critical period for the treatment of amblyopia in light of recent experimental and clinical evidence for neural plasticity. Specifically, adults with amblyopia can improve their perceptual performance via extensive practice on a challenging visual task, and this improvement may transfer to improved visual acuity Ambl yopes achieve this improvement via the mechanisms that have been shown to explain perceptual learning in the normal visual system. It is hypothesized that these same mechanisms account for at least some of the improvement that occurs in the treatment of amblyopia. (c) 2005 Wiley Periodicals, Inc.
