Comparison of different positioning techniques for reduction of induced vertical deviation following Nishida procedure for the treatment of sixth nerve palsy.

ABSTRACT:

Purpose

Induced vertical deviation is a potential complication following the Nishida procedure for the treatment of sixth nerve palsy. This study aims to compare different positioning techniques for the reduction of this complication.

Methods

We retrospectively examined medical records from consecutive patients who underwent the Nishida procedure, classifying them into three positioning groups: intra-quadrant (IQP), lateral rectus border (LRBP), and horizontal meridian (HMP). Surgical and pre/postoperative data were compared.

Results

Among the 27 included patients (8 IQP, 9 LRBP, 10 HMP), all three groups demonstrated similar reductions in esodeviation: IQP, 44.0 ± 18.7 Prism Diopters (PD); LRBP, 42.2 ± 15.3 PD; HMP, 42.2 ± 7.8 PD; (P = 0.675). After surgery, one pati
