Long-term results of unilateral lateral rectus recession in intermittent exotropia
1Guru Nanak Eye Center, Maulana Azad Medical College, New Delhi 110002, India.
Purpose:
Unilateral lateral rectus recession is an alternative procedure in the treatment of moderate angle intermittent exotropia. However, long-term results of unilateral lateral rectus recession have not yet been studied. The aim of this study was to determine the long-term stability of alignment following unilateral lateral rectus recession in patients with intermittent exotropia with a deviation of 25 to 30 PD.
Patients And Methods:
Thirty-two patients with intermittent exotropia with a deviation of 25 to 30 PD were included in this study. All patients underwent 8-mm unilateral lateral rectus recession by conventional techniques.
Results:
Satisfactory results (+/- 5 PD of orthophoria) were obtained in 77.7% of the patients after a 3-year follow-up period. The mean correction achieved was 22.9 PD.
Conclusion:
Our results indicate that 8-mm unilateral lateral rectus recession is an attractive alternative procedure in the treatment of intermittent exotropia with a deviation of 25 to 30 PD.
