Temporal performance parameters vary across the visual field. Their topographical distributions relative to each other and relative to basic visual performance measures and their relative change over the life span are unknown. Our goal was to characterize the topography and age-related change of temporal performance. We acquired visual field maps in 95 healthy participants (age: 10-90 years): perimetric thresholds, double-pulse resolution (DPR), reaction times (RTs), and letter contrast thresholds. DPR and perimetric thresholds increased with eccentricity and age; the periphery showed a more pronounced age-related increase than the center. RT increased only slightly and uniformly with eccentricity. It remained almost constant up to the age of 60, a marked change occurring only above 80. Overall, age was a poor predictor of functionality. Performance decline could be explained only in part by the aging of the retina and optic media. In Part II, we therefore examine higher visual and cognitive functions.
时间性能参数在整个视野范围内各不相同。它们相对于彼此以及相对于基本视觉性能指标的地形分布，以及它们在整个生命周期中的相对变化尚不清楚。我们的目标是描述时间性能的地形特征和与年龄相关的变化。我们获取了95名健康参与者（年龄：10 - 90岁）的视野图：视野阈值、双脉冲分辨率（DPR）、反应时间（RTs）和字母对比度阈值。DPR和视野阈值随离心率和年龄增加；周边区域与年龄相关的增加比中心区域更明显。RT仅随离心率略有且均匀地增加。在60岁之前它几乎保持不变，只有在80岁以上才会出现明显变化。总体而言，年龄对功能的预测能力较差。性能下降只能部分归因于视网膜和光学介质的老化。因此，在第二部分中，我们将研究更高层次的视觉和认知功能。
