An augmented Anderson surgical procedure corrected face turn and improved visual acuity in a study in patients with idiopathic infantile nystagmus.

Pradeep Sharma, MD, MNAMS, and colleagues at the Dr. Rajendra Prasad Centre for Ophthalmic Sciences, New Delhi, evaluated the augmented Anderson procedure in 12 consecutive patients, aged older than 5 years, with idiopathic infantile nystagmus with eccentric null position and anomalous head position.

The augmented Anderson procedure involves recessing the medial and lateral rectus muscles. After surgery, all children showed significant improvement in head position (P = .0001), and binocular visual acuity improved in primary position (P = .007). No child developed more than mild limitation of horizontal movements, according to the study.

At 3 months' follow-up, the nystagmus intensity in the primary position had significantly decreased (P = .006) from 22° ± 15.9° cycles/sec preoperatively to 10.6° ± 10.2° cycles/sec, according to the study.

The study is published in the August issue of the Journal of the American Association for Pediatric Ophthalmology and Strabismus.
