一个并不罕见的发生在老年人的发展是一个“黄斑孔”，但很少有心理物理观察已在这种情况下。我在这里描述了一些扭曲的图像时，我看到的对象与我的右眼有一个黄斑孔的经验。物体通过向中央凹收缩而变形。因此，圆盘保持其形状，但变得更小，而线被破坏或弯曲。通过与动物实验的类比，我们认为知觉的变化是由于视觉皮层的生理变化。(C)1999 Elsevier Science Ltd.保留所有权利。
A not uncommon occurrence in elderly people is the development of a 'macular hole' but very few psychophysical observations have been made in such cases. I describe here some distortions of image experienced when I view objects with my right eye which has a macular hole. Objects are distorted by being shrunk towards the fovea. Thus, a disc retains its shape but becomes smaller whereas lines are broken or bent. By analogy with animal experiments it is suggested that the perceptual changes are due to physiological changes in the visual cortex. (C) 1999 Elsevier Science Ltd. All rights reserved.
