Description of intervention(s) / exposure
Image tilt (torsion) will be observed using
three commonly used clinical measures of torsion; the synoptophore, double Maddox rod and Torsionometer. These three tests all measure in degrees the amount of torsion as subjectively indicated by the participant.

Summary
Brief summary
The purpose of this study is to investigate the difference in torsion in primary position (head straight, looking straight ahead) and compare it to measurements in 15 and 30 degrees in downgaze (head straight, eyes looking downwards). It is hypothesised that torsion will increase in downgaze, especially in cases of bilateral superior oblique palsy. Therefore, we hope to establish an amount of torsion that differentiates bilateral and unilateral superior oblique palsy. This will help clinicians plan treatment and hopes to avoid cases of "masked" superior oblique palsy (where after surgery for a unilateral superior oblique palsy, a superior oblique palsy is uncovered in the other eye).
