ABSTRACT
PURPOSE:
To evaluate the efficacy of modified Anderson procedure in infantile nystagmus with face turn less than 30 degrees.METHODS:
This study was a retrospective review of the medical records of 13 consecutive patients who underwent a modified Anderson procedure for abnormal head position in infantile nystagmus at Pusan National University hospital from February 2002 to March 2017. We compared best-corrected visual acuity (logarithm of minimal angle of resolution, logMAR), refraction, degree of face turn, ocular motility, and angle of deviation preoperatively and at 1 week postoperatively, 6 months postoperatively, and the final visit. Recession of the yoke rectus muscles responsible for the slow phase of nystagmus was performed, depending on the direction of face turn; the medial rectus muscle of the eye to which the head was turned was recessed 10 mm, whereas the lateral rectus muscle of the contralateral eye was recessed 12 mm.RESULTS:
The mean age of the patients was 8.9 (2–25) years, and the mean follow-up period after surgery was 51.3 (6–183) months. Twelve patients (92.3%) had no residual head posture or <10° at 6 months postoperatively, and three patients (23.1%) achieved this outcome with an additional operation. The mean degrees of face turn were 22.30° before surgery and 3.85° post-operatively (p = 0.001). Best-corrected visual acuity (logMAR) was 0.41 in the better eye and 0.50 in the worse eye before surgery; this improved to 0.34 and 0.45 at 6 months postoperatively (p = 0.068 and p = 0.228, respectively). Despite the large recessions involved, only one patient showed mild limitation of abduction after surgery.CONCLUSIONS:
The modified Anderson procedure may be effective for correcting abnormal head position in infantile nystagmus with face turn less than 30 degrees; patients were not overcorrected.
