PURPOSE: To report the surgical effect in upshoot of Duane retraction syndrome (DRS) with corecession of horizontal rectus muscles with or without Y-splitting.
PATIENTS AND METHODS: A retrospective chart review of six patients of DRS received muscle surgeries for upshoot in adducted position was performed.
RESULTS: From 1994 to 2010, six Duane patients received muscle surgeries for upshoots of lesion eye in adduction. Their age of receiving surgery ranged from 5 to 41 years. Four of the patients were male, and five had their left eye involved. Three underwent recession of ipsilateral medial and lateral rectus (LR) muscles, and the other three also received Y-splitting of LR muscle when recession. One of the patients that received Y-splitting showed mild hypertropia at down gaze postoperatively, and another one had little improvement of exotropia at the primary position. All patients showed improvement of their upshoots and lid fissure narrowing in adduction as well as face turn.
CONCLUSION: Postoperative improvements in abnormal head posture and upshoots were achieved with corecession of horizontal muscles with or without Y-splitting. Although Y-splitting of the LR muscle is an effective surgery, it might cause undesired complications.
