چکیده انگلیسی
A 43-year-old man with infantile nystagmus syndrome complained of “head tremor” that would occur during attempted reading. Three-dimensional, combined eye and head recordings were performed with the magnetic search coil technique in two conditions: 1) looking straight-ahead under photopic conditions without a particular attentional focus and 2) reading a simple text held one meter away. A mainly vertical-horizontal spontaneous nystagmus was evident in both conditions, whereas head nodding emerged in the second condition. The head oscillated only in the vertical plane and concomitant analysis of eye and head displacement revealed a counterphase, compensatory pattern of the first harmonic of the INS waveform. This was verified by the significant negative peak of the crosscorrelogram at zero lag. Eye-in-space (gaze) displacement during nystagmic oscillations was thereby reduced suggesting a central adaptive behavior that may have evolved to partly compensate for the abnormal eye movements during reading.
