Ocular symptoms have been evaluated on a VDT operators group, by using questionnaires and an ophthalmological screening. The results show that some ocular fatigue symptoms are much more frequent in VDT operators in comparison with the control group. VDT operators working more than 4 hours/day at VDT are the most affected.
The incidence of psychosomatic symptoms in a group of VDT operators is evaluated and compared with a control group (people not working at VDTs) by using questionnaires. The dta show that some psychosomatic symptoms are much more frequent in VDT operators in comparison with the control group.

The results of a study on 68 VDT operators are hereby presented. Various biochemical indexes are evaluated as markers of stress. In particular, urinary catecholamines and their metabolites (E, NE, DA, HVA, VMA), ACTH, cortisol, NEFA and fructosamine have been tested by the Authors. Each assay has been performed both in basal conditions, and after the completion of subjects workshift, taking into account the normal hormonal biorhythms. The data which emerged have been analyzed by statistical method ("Student t" with coupled data). Each subject data was confronted before and after workshift. The number of hours of VDT exposure and the different types of duties have been considered and evaluated. The results show that, although the data are all included within the normal range, some of the tested parameters after workshift are significantly higher, compared with the same parameters referring to the basal condition. In particular, Epinephrine and Norepinephrine seem to be the most effective markers of stress. Analogous studies will be pursued in the future by the Authors on a larger number of VDT operators.

A review of data resulting from the studies on health aspects of VDT operators is hereby presented and discussed by the Authors. In particular, researches on visual, musculoskeletal, dermatological and reproductive system alterations in VDT operators, together with psychological aspects, are evaluated and problems involved in radiation emission from VDTs are exposed too. Preventive measures are mentioned. According to the majority of the studies--up to now--no valid evidence of any abnormalities has been provided that can be specifically attributed to VDT work. The necessity of further researches on psycho-organic aspects of work with VDT is suggested by the Authors.
Occupational stress is defined and the main problems involved in the study of stress in VDT operators are pointed out and discussed. A preliminary research is presented, in which urinary catecholamines and fibrinolysis are tested in a group of VDT telephone operators. Basal values are compared with data obtained after a work shift. No evident difference appears from this evaluation.
The prevalence of psychosomatic symptoms in a group of VDT telephone operators is evaluated and compared with a control group (people not working at VTDs), by using questionnaires. The results show that psychosomatic symptoms are much more frequent in VDT operators in comparison with the control group.
