Base-In/Base-Out Jump Duction Slides

These card sets are colored landscape line drawings for testing and training children and adults with saccadic fusional movements (jump ductions). This type of skill is essential to all patients since it comes closest to the manner in which the eyes are usually moved in everyday life.

Surrounding each target are numbers that match up with different pieces of the target image. These pieces appear progressively closer as the numbers increase. Additionally, tick marks are used within the oval numbers to prove no foveal suppression and slip in fixation exists.
