[The scanning laser ophthalmoscope and its application as a measuring system for eye movements]

This paper describes the present status of scanning laser ophthalmoscopy (SLO) for three-dimensional recordings of monocular eye movements. The measurement principle is based on tracking suitable landmarks on either the ocular fundus or the anterior eye pole. In addition, since it incorporates a special feature allowing the projection of visual test stimuli onto precisely controllable locations of the retina, SLO introduces a novel method of studying the relationship between retinal activity and eye movement analysis. The clinical use of SLO for the evaluation of vestibular otolith function by measuring the rotation of the ocular fundus image in response to lateral head tilt (ocular counterrolling reflex, OCR) is illustrated.
