Abstract
Purpose:
The aims of this study were to assess the clinical features of strabismus and the surgical results of the strabismus in periventricular leukomalacia(PVL) patients.
Methods:
The retrospective chart review was performed on the 60 patients diagnosed as periventricular leukomalacia from 2007 to 2011 at our center. Factors including type of strabismus, age at surgery, gender, preoperative maximum deviation, type of surgery, and alignment at postoperative 6 months were investigated. Success was defined as the postoperative alignment from esotropia(ET) 10 PD to exotropia(XT) 10 PD.
Results:
A total of 60 patients with an average age of 3.3 years (range, 0.2 to 18.3 years) were included. Thirty patients (50.0%) had strabismus. Seventeen (28.3%) and 12 (20.0%) of 30 patients exhibited XT and ET. Seven(11.7%) patients had vertical strabismus. Ten patients had shown strabismus newly during follow-up period. Of the 10 patients, 4 had XT, 5 had ET, and 1 had XT with hypertropia. As a result, Total 39(65%) of 60 PVL patients had strabismus. The 15 patients underwent strabismus surgery at a mean age of 3.7 years. Of the 15 patients, 4 had XT, 6 ET, 5 XT with hypertropia. At the postoperative 6 months, 11 of the 15 patients showed a deviated angle less than 10PD. The success rate was 73.3%.
Conclusions:
In PVL patients, The prevalence rate of strabismus was higher than healthy subjects and strabismus was showed newly during follow-up period. Therefore, we need a more careful examination of strabismus and a long term follow-up.
