[Surgical treatment of congenital nystagmus in children]

The paper describes results after surgical treatment of congenital nystagmus in 47 patients, aged 6--16 years; of them 34 patients had a jerk nystagmus with a neutral zone in the dextro- or levoversion and a forced position of the head, and 13 had a pendular nystagmus. In case of jerk nystagmus, bilateral recession--resection of horizontal muscles after Helveston was made, and in case of pendular nystagmus--a "faden-operation" after Cüppers. In most of patients (80%) the effect was positive: improvement of head position, decrease of nystagmus amplitude, increase of visual acuity. The best results were achieved in patients with jerk nystagmus. The authors recommend to use surgical treatment of congenital nystagmus in a more wider scale.
