Sympathetic ophthalmia presenting 5 days after penetrating injury.

Purpose: To describe a rare case of early sympathetic ophthalmia that presented 5 days after penetrating injury.

Observations: A 13-year-old boy presented with a penetrating left globe injury from a BB metallic projectile that was emergently repaired. Five days later, routine dilated exam of the right eye revealed interval development of vitritis over the posterior pole.

Age-related preservation of top-down control over distraction in visual search.

Visual search studies have demonstrated that older adults can have preserved or even increased top-down control over distraction. However, the results are mixed as to the extent of this age-related preservation. The present experiment assesses group differences in younger and older adults during visual search, with a task featuring two conditions offering varying degrees of top-down control over distraction.

Adult age differences in functional connectivity during executive control.

Task switching requires executive control processes that undergo age-related decline. Previous neuroimaging studies have identified age-related differences in brain activation associated with global switching effects (dual-task blocks versus single-task blocks), but age-related differences in activation during local switching effects (switch trials versus repeat trials, within blocks) have not been investigated. This experiment used functional magnetic resonance imaging (fMRI), and diffusion tensor imaging (DTI), to examine adult age differences in task switching across adjacent trials (i.
