Chun BY, Kang KM - J Ophthalmol (2015)

Bottom Line: The mean age of the patients was 9.2 years.The preoperative mean deviation angle was 32.4 PD at distance and 43.4 PD at near.In addition, the mean difference between distance and near deviation angles was significantly reduced from 11 PD to 1.4 PD at 6 months postoperatively.

ABSTRACT
The aim of this study was to evaluate the efficacy of slanted recession of the lateral rectus muscle for intermittent exotropia with convergence insufficiency. This prospective study included 31 patients who underwent slanted lateral rectus recession for intermittent exotropia with convergence insufficiency between June 2010 and June 2012. Following parameters were recorded and analyzed: patient sex, age, preoperative and postoperative near and distance ocular alignment, and changes in stereopsis. The mean age of the patients was 9.2 years. The preoperative mean deviation angle was 32.4 PD at distance and 43.4 PD at near. After 6 months, slanted lateral rectus recession reduced the deviation angles to 2 PD at distance and 3.4 PD at near. In addition, the mean difference between distance and near deviation angles was significantly reduced from 11 PD to 1.4 PD at 6 months postoperatively. Slanted lateral rectus recession for intermittent exotropia with convergence insufficiency in children successfully reduced the distance and near exodeviations and the near-distance difference without increasing the risk of long-term postoperative esotropia or diplopia.

fig1: Slanted lateral rectus muscle recession. The upper pole was recessed according to the distance exodeviation and the lower pole was recessed according to the near exodeviation.

Mentions: All patients were operated on by the same surgeon (BYC). Under general anesthesia, slanted LR recession was performed through a temporal limbal peritomy. In the slanted LR recession, the new insertion was created in an oblique fashion in comparison with the original insertion (Figure 1). The upper pole of the LR muscle was recessed according to the distance deviation angle (from 6.5 to 8.5 mm). The lower pole of the LR muscle was recessed according to the near deviation angle (from 8.0 to 9.5 mm); the lower pole was recessed more than the upper pole, as the deviation was greater at near than at distance (from 1.0 to 2.0 mm) [1]. The extent of the recession was primarily based on the length indicated by surgical tables derived from Parks.
