Summary
A surviving patient with two rare types of abnormal eye movements, typical ocular bobbing and subsequently developed intermittent vertical oscillations of the eyes, is described, and a follow-up series of electro-oculographic recordings of these eye movements is analyzed. It is suggested that these two types of vertical eye movements might have a common pathophysiological background and the activity of remaining functional oculomotor pathways may play an important role in their occurrence.
Zusammenfassung
Es wird ein Patient beschrieben, bei welchem zwei seltene Typen von abnormen Augenbewegungen vorhanden waren: zunächst typisches “ocular bobbing” und anschließend intermittierende vertikale Oszillationen der Augen. Es wurde eine Serie von elektrooculographischen Registrierungen dieser Augenbewegungen analysiert. Aus der Beobachtung wird gefolgert, daß diese beiden Typen von vertikalen Augenbewegungen eine gemeinsame pathophysiologische Grundlage haben könnten. Es wird angenommen, daß die Funktion von verbleibenden oculomotorischen Bahnen beim Zustandekommen dieser Augenbewegungen eine wichtige Rolle spielen könnte.
