OBJECTIVES: As we age, the functional field of view (FFOV) declines and these declines predict falls and motor vehicle accidents in older adults (Owsley, 2013). To increase understanding of possible causes of this decline, the current study explored whether the functional field of view in older adults is associated with the sensitivity of the magnocellular and parvocellular sub-cortical pathways. METHODS: Forty four younger (M = 27.18, SD = 5.40 years) and 44 older (M = 72.18, SD = 5.82 years) adults completed a FFOV test and the steady and pulsed pedestal paradigms of Pokorny and Smith (1997) as measures of magnocellular and parvocellular pathways, respectively. RESULTS: Older adults made more FFOV errors and had higher contrast discrimination thresholds in both the steady and pulsed pedestal paradigms, than younger adults. FFOV errors in the younger group were not related to contrast discrimination thresholds. In multiple regression, older group FFOV errors showed a strong unique association with contrast discrimination thresholds mediated via the magnocellular, but not the parvocellular pathway. DISCUSSION: We infer that reduced magnocellular pathway contrast sensitivity may contribute to reduced functional vision in older adults.
