Abstract

The nystagmus-detection rates with Frenzel's spectacles (FS), infrared CCD camera (CCD), and electronystagmography (ENG) were compared and studied.<BR>In an examination of 1118 subjects, the nystagmus-detection rate with CCD was 13.2 times higher than that with FS.<BR>In 367 of the 1118 subjects the nystagmus-detection rates of all three techniques were compared.<BR>When the number of subjects in whom FS produced the same detection rate as ENG, and the number of subjects in whom CCD produced the same detection rate as ENG were compared, CCD was 2.5 times better than FS.<BR>The nystagmus-detection rate with ENG was 34.2 times that with FS and 13.5 times that with CCD.<BR>Studies and comparisons revealed the advantages and disadvantages of FS, CCD, and ENG. It is necessary to evaluate not only their nystagmus-detection rates, but also each device's merits and to take full advantage of their strengths.
