Abstract:
PURPOSE: To evaluate the effect of 9 mm and 7 mm bilateral recession of the superior rectus muscle in patients with bilateral dissociated vertical deviation (DVD) who had a deviation difference between the non-fixing and fixing eyes of less than 8PD. METHODS: The subjects were chosen from the patients who visited our hospital for DVD between January 2001 and November 2003. We reviewed the surgical records of 19 patients who had undergone 9 mm recession of superior rectus muscle in the non-fixing eye and 7 mm in fixing eye, and who had been followed up for at least 6 months. RESULTS: A residual DVD less than 8PD was regarded as successful. The overall success rate was 73.7%. The success rate of 10~14PD preoperative deviation of the non-fixing eye was 80.0%, and that of 15~19PD preoperative deviation of the non-fixing eye was 75.0%. However, the success rate was 66.7% in recession for the deviation over 20PD. CONCLUSIONS: Bilateral recession of 9 mm and 7 mm of the superior rectus muscle was effective for bilateral DVD in which the deviation difference of the non-fixing eye and fixing eyes was less than 8PD.
