[Stereoacuity before and after surgery in patients with acquired excyclotorsion].
OBJECTIVE
To investigate the stereoacuity before and after superior oblique sagittal transposition in patients with acquired excyclotorsion.


METHODS
14 cases of acquired excyclotorsion who had complaints of forward and downward torsional diplopia were treated with superior oblique sagittal transposition. All patients were examined with Titmus test prior and after surgery.


RESULTS
Surgical treatment greatly improved torsional diplopia. The stereoacuity improved gradually from 800 to 60 seconds of arc, peripheral to macular stereoacuity, and even foveal stereoacuity.


CONCLUSIONS
The superior oblique sagittal transposition is an effective method for primary and down gaze acquired excyclotorsion. The operation not only alleviated diplopia in the practical fixation field, but also improved stereoacuity.
