Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

With this study the investigator wants measure the individual cyclofusion competence from healthy subjects and patients suffering from Strabismus with a only binocularly visible threedimensional Landolt-C stimulus. For this the participant has to look at a 3-D monitor with shutter glasses. The participant is sitting in 2 meter distance in front of the monitor. On the monitor appears the Landolt-C stimulus as a dynamic Random-Dot Stimulus. As long as the participant can fuse the stimulus he will be able to see the Landolt C-ring threedimensional. The participant is then ask to tell in which direction the notch of the Landolt-C ring points out. Once a critical degree of cyclotorsion is reached the participant will no longer be able to see the Landolt C ring and the individual cyclofusion competence is reached.
