title: Diagnostic features of retinal nerve fiber layer rotation in skew deviation using optical coherence tomography.
abstract: A 41-year-old woman with skew deviation had cyclotorsion of both eyes. This resulted in a falsely low probability plot of retinal nerve fiber layer thickness in adjacent clock hours on optical coherence tomography (OCT) due to displacement of the retinal nerve fiber layer peaks. Ocular cyclotorsion may cause misinterpretation of OCT probability plots. OCT retinal nerve fiber layer plots also may be used to objectively quantify the degree of ocular cyclotorsion.
