时间性能参数在整个视野中有所不同。它们相对于彼此的地形分布、相对于基本视觉表现测量的分布以及它们在生命周期内的相对变化都是未知的。我们的目标是描述时间表现的地形和年龄相关的变化。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 (RT) 和字母对比度阈值。 DPR 和视野阈值随着偏心率和年龄的增加而增加；外围地区比中心地区表现出更明显的与年龄相关的增长。 RT 仅随偏心率轻微且均匀地增加。直到 60 岁，它几乎保持不变，只有 80 岁以上才会发生显着变化。总体而言，年龄对于功能的预测效果不佳。性能下降只能部分解释为视网膜和视神经介质的老化。因此，在第二部分中，我们检查更高的视觉和认知功能。
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.
