Primary Outcome Measures

Name	Time	Method
Degree of cyclodeviation measured by SD-OCT (spectral domain optical coherence tomography) with an anatomical positioning system (APS) and measured at the harms tangential Screen by the patients with primary oblique muscle overaction or trochlear palsy.<br>The measurements are carried out during the examination of the patients / healthy subjects from the regular consultation hours.

Secondary Outcome Measures

Name	Time	Method
Examination of cyclotorsion by SD-OCT and Harms tangent screen by the healthy subjects and comparison with patients with primary oblique muscle overaction or superior oblique palsy.<br>Change of cyclotorsion with a different fixation: 1 Fixation with the affected eye. 2. Fixation with the healthy eye.<br>The measurements are carried out during the examination of the patients / healthy subjects from the regular consultation hours.
