Visual perseveration and palinopsia are defined as the persistence or the reappearance of the visual image. These infrequent symptoms are thought to be linked to the right hemisphere posterior areas. We report a case of this syndrome in which the initial fixation was foveal. The palinoptic image was sometimes moving. This suggests that palinopsia is due to a dysfunction of the visual memory, rather than of the visual system: this dysfunction may be related to hyperactivity of the visual buffer.
视觉留存和视觉后像被定义为视觉图像的持续存在或再次出现。这些不常见的症状被认为与右半球后部区域有关。我们报告了一例该综合征病例，其最初注视点为中央凹。视觉后像有时会移动。这表明视觉后像是由于视觉记忆功能障碍，而非视觉系统功能障碍：这种功能障碍可能与视觉缓冲器的过度活跃有关。
