Superior oblique tuck: A self-dosing procedure appropriate for all classes of superior oblique palsy

Abstract

Superior oblique palsy is a common cause of vertical and torsional strabismus. Knapp distinguished 6 classes, based on the direction of gaze in which the maximum deviation occurs. Different surgical procedures have been advocated for different classes. We report a sequential case series of superior oblique palsies of all types, all treated with the same procedure: a superior oblique tuck, dosed according to intraoperative traction testing and an adjustable recession of the contralateral inferior rectus.
