简要总结
Pre-Study: Evaluation of the inter- and intrarater reliability of the integrated algorithm by Heidelberg Spectralis for measuring cyclotorsion on SLO-fundus fotographs, and assessment of the influence of measuring with or without eye tracker.
Study: Comparison of cyclotorsion measurements in patients with forth nerve palsy and in healthy controls on SLO-fundus fotographs using the integrated algorithm by Heidelberg Spectralis
