Upper Depth Limit Across Visual Field

Stereopsis is important for tasks of daily living such as eye-hand coordination. It is best in central vision but is also mediated by the periphery. Previously we showed that individuals with central field loss, but  who have residual stereopsis in the periphery perform better at an eye-hand coordination task when they perform the task binocularly rather than monocularly. In this project, we seek to determine what sets the limit of stereopsis, defined as the largest disparity that supports the sustained appearance of depth, in the near periphery in healthy individuals.


This project is now completed. Please see the Publication section for results.
