Brief Summary:
The purpose of this research study is to learn how people distribute their visual attention when looking at objects nearby versus far away and why vision may become distracted at near versus far distances
Detailed Description:
Visual distraction is a problem that more often occurs people who have suffered strokes than in the general population Problems of visual attention generally appear immediately following a stroke and may impair driving and other functions While it is thought that there is a natural course of improvement over time little is known about how this improvement occurs Some studies suggest that recovery is only partial meaning certain aspects of visual attention may improve while other aspects remain but escape notice
The purpose of this study is to examine the effect of stroke on a persons visual attention when looking at objects nearby versus far away and to learn why a persons visual attention may become more distracted at near versus far distances The purpose of this study is also to understand how modeled interventions such as eye patching or prism goggles affect impairment measures of visual attention
After an initial screening including attention thinking memory and visual judgment tests participants will be given a neurological examination Participants may be asked to perform visual tasks while wearing an eye patch or prism goggles Next they will be asked to perform a line bisection task by looking at lines on a video screen either at close or far distances and using a laser pointer marking the center of the lines as they appear on-screen Participants may be asked to perform other similar visual tasks as well
Duration of the study for participants varies ranging from 1 or 2 sessions totaling approximately 2 hours to multiple sessions spanning a year
Research from this study may help researchers better understand problems associated with stroke and may lead to therapies designed to promote improved visual attention
