Divergence Excess Intermittent Exotropia: Long-Term Effect of Augmented Bilateral Lateral Rectus Recession

To investigate the long-term (10 years) effects of augmented bilateral lateral rectus (aBLR) recession in patients affected by divergence excess intermittent exotropia (deIXT). Data of 58 patients affected by deIXT who underwent aBLR muscle recession were retrospectively analyzed. All patients were...

Description
Summary:To investigate the long-term (10 years) effects of augmented bilateral lateral rectus (aBLR) recession in patients affected by divergence excess intermittent exotropia (deIXT). Data of 58 patients affected by deIXT who underwent aBLR muscle recession were retrospectively analyzed. All patients were treated with 8.0 to 9.5 mm (mean 8.6 ± 0.5 mm) recession of BLR. Our result showed a significant decreasing of both distance and near residual deviation during follow-up. The percentage of patients with successful surgical outcome (defined as a residual deviation ranging from 10pd intermittent exotropia to 5pd esotropia) increased during follow-up (from 51.7% to 81% at last follow-up). Stereopsis increased in 39.7% of patients at last follow-up. Moreover, there was a significant correlation between age at surgery and short/mid-term residual deviation. Our long-term results suggest that aBLR recession surgery is a very effective approach in patients affected by deIXT.
