[Electronystagmographic evaluation of surgical results in nystagmus treatment]

In the management of congenital, ocular nystagmus as well surgical procedures (according Kestenbaum, Anderson and similar modifications) with the purpose of shifting nystagmus "neutral zone" in the primary position of gaze, as nonsurgical treatment with prisms, show favourable effect on head position, nystagmus intensity and visual acuity. In this preliminary report the authors tried to evaluate, by means of electronystagmography, their clinical experiences in some treated nystagmus cases, objectively. The electronystagmographic findings of nystagmus amplitude, frequency and intensity, depending on position of gaze, were before and after surgery, respectively treatment analysed.
