Results of a new operation in the treatment of nystagmus

: A new surgical procedure is presented (Avietisov 1978) which in contrast to the Anderson-Kestenbaum method may be used in nystagmus of every kind. The essential element of this procedure is the resection of the anterior belly of the eye muscles comprising the neuro-muscular spindles responsible for the local mechanisms regulating the action of the oculomotor muscles. Application of this method in 76 patients caused a decrease of the nystagmus amplitude in all types of this condition. The discussed operation did not however influence the frequency of the ocular movements. The performed surgical procedure lead to an improvement of the visual acuity and of the position of the head.
