Abstract
We developed a new recording system of eye movement with a CCD image-sensor in a video-camera. We showed that CCD-EOG is a valuable caloric test. In comparison with caloric tests using conventional methods, caloric testing with CCD-EOG has some advantages : 1. Eye movenents can be watched on a green display, where it is easier to measure the duration of nystagmus. 2. No dark adaptation is needed in recording : change of light does not affect the recording of eye movements. 3. Quantitative analysis is easier because the data are stored on a floppy disk and the recording system is precise.
