关于聚散度和斜视系统的发育可塑性知之甚少，这是一个重要的问题，因为异常会导致视觉问题，例如斜视。人工改变调节和聚散之间的联系的一种方式是改变对聚散的刺激，同时固定调节刺激，如在虚拟现实显示器中发现的。虽然在这种情况下研究发育可塑性是有意义的，但由于许多儿童接触使用这种安排的游戏机，迄今为止还没有研究解决这个问题。然而，有迹象表明，成年人长期观看VR可能会导致视觉问题。在这些系统被广泛使用之前，确定它们对发展中的人类视觉系统的安全性显得非常重要。本文讨论了成人的调节和聚散系统的适应性以及VR观看的效果。稀疏的文献在儿童适应，然后进行审查，并提出建议的方法，将提高我们的知识可塑性的调节和儿童聚散。(C)1998爱思唯尔科技有限公司版权所有。
Little is known about the developmental plasticity of the vergence and accommodative systems, an important issue since abnormalities can lead to visual problems, e.g. strabismus. One way of artificially altering the links between accommodation and vergence is to vary the stimulus to vergence while fixing the accommodative stimulus, as is found in virtual reality displays. While it would be of interest to study developmental plasticity in this situation, since many children are exposed to games machines which use this arrangement, no studies to date have tackled this issue. There is, however, some indication that long-term VR viewing in adults can lead to visual problems. It seems important to determine the safety of these systems for the developing human visual system before they come into common use. In this paper, adaptation of the accommodation and vergence systems and the effect of VR viewing in adults is discussed. The sparse literature on adaptation in children is then reviewed, and suggestions made for approaches that would enhance our knowledge of plasticity of accommodation and vergence in children.
