[Lacrimal hyposecretion in women working with video terminals]

Tests of vision and lacrimal secretion were performed as part of a general medical check-up among women employed at video-terminals in a bank. The tests were taken by three groups of 100 employees each. The first group consisted of full-time (eight hours) employees, the second of those working part-time (the time spent at a video-terminal daily was never less than two hours of continuous work) and a third group of control subjects having different clerical jobs but working in the premises with video-terminals. Diminished lacrimal secretion was most often present among full-time workers (20 per cent). A statistically significant difference in lacrimal secretion was observed between the first and the second group of examinees. There was no significant difference between the second group and the controls.
