  • Title: Evaluation of vergent eye movement using the jumping method.
    Author: Iwasaki T, Kurimoto S.
    Journal: J UOEH; 1987 Jun 01; 9(2):133-9. PubMed ID: 3616258.
    Abstract:
    The state of vergent eye movement is reported before and after the experimental work. The work performed by 26 subjects was a name search task on a visual display terminal (VDT). Convergence and divergence eye movements were recorded objectively using an accommodopolyrecorder, and as a sensor of eye movement, elictro-oculogram (EOG) was applied. These eye movements were elicited by watching each target, a far fixation target and a near fixation target, which alternated from far to near every five seconds on the accommodopolyrecorder. Measurements by this method were conducted at two points in time: before beginning the VDT work and after completing the work. The convergence time was unchanged before and after the work load. The divergence time, however, was prolonged after the work load, which was highly significant (P less than 0.001). In this study, it is shown that the vergent eye movement, convergent and divergent eye movement, is influenced by VDT work.
