In healthy vision, the fovea provides high acuity and serves as the locus for fixation achieved through saccadic eye movements. Bilateral loss of the foveal regions in both eyes causes individuals to adopt an eccentric locus for fixation. This review deals with the eye movement consequences of the loss of the foveal oculomotor reference and the ability of individuals to use an eccentric fixation locus as the new oculomotor reference. Eye movements are an integral part of everyday activities, such as reading, searching for an item of interest, eye–hand coordination, navigation, or tracking an approaching car. We consider how these tasks are impacted by the need to use an eccentric locus for fixation and as a reference for eye movements, specifically saccadic and smooth pursuit eye movements.

黄斑变性中的眼球运动

在健康的视力中,中央凹提供高敏锐度,并作为通过眼球扫视运动实现的固定位置。双眼中央凹区域的双边损失导致个体采用偏心轨迹进行固定。这篇综述讨论了中心凹动眼神经参考缺失的眼球运动后果以及个体使用偏心注视点作为新动眼神经参考的能力。眼球运动是日常活动不可或缺的一部分,例如阅读、搜索感兴趣的项目、手眼协调、导航或跟踪接近的汽车。我们考虑了这些任务如何受到使用偏心轨迹进行固定的需要以及作为眼球运动的参考的影响,特别是扫视和平滑的追踪眼球运动。
