A Novel New [Yet Again ] Procedure for Correction of

ABSTRACT: Purpose: To evaluate the effectiveness of an augmented Anderson procedure
combined with tenotomy and reattachment of the remaining horizontal rectus muscles in
correcting horizontal compensatory head posture associated with idiopathic infantile nystagmus.
Methods: Clinical records of five subjects with horizontal compensatory head posture
secondary to infantile nystagmus who underwent an augmented Anderson procedure combined
with tenotomy and reattachment of the remaining horizontal rectus muscles were
retrospectively reviewed. The main outcome measures were angular reduction of head turn,
nystagmus reduction, and visual acuity.
Results: The mean preoperative head deviation of 19.6 degrees decreased 79% to a
postoperative mean of 4.2 degrees. No patient was overcorrected. Nystagmus was decreased
in four of five subjects. Visual acuity improved by one Snellen line or more in three eyes,
improved less than one Snellen line in two eyes, and was unchanged in five eyes.
Conclusions: An augmented Anderson procedure combined with tenotomy and
reattachment of the remaining horizontal rectus muscles is safe and effective in reducing both
abnormal compensatory head posture and nystagmus in idiopathic infantile nystagmus with
minimal risk of overcorrection.
