Abstract

<h4>Purpose</h4>Fell's modification of the Harada-Ito (HI) procedure is often used to tackle subjective torsion usually following superior oblique palsy. There is limited published data on the longer-term outcomes and the effect on horizontal incomitance of the procedure. The purpose of this study is to report on the medium to long-term outcomes of the HI procedure.<h4>Materials and methods</h4>A retrospective review of 20 patients who had all undergone a single surgeon modified HI procedure to correct subjective torsion was undertaken. Follow-up data were analyzed in relation to stability of torsion measurements, the effect on vertical incomitance of horizontal deviation and the final treatment outcome.<h4>Results</h4>There was a significant reduction in median maximum torsion from preoperative to immediately post-op (<i>p</i> < .01) and there remained a significant difference in maximum torsion from preoperative measurement at both the 3-month (<i>p</i> = .02), and 12-twelve month (<i>p</i> = .01) follow-up. HI had a significant effect on associated V-pattern esotropia (<i>p</i> < .05).<h4>Conclusion</h4>The HI procedure is effective in eliminating subjective torsion initially and reducing incomitant horizontal deviation; however, regression toward preoperative torsion measurement occurs after time.
