Trends regarding myopia in video terminal operators.
A longitudinal study with a 4-year follow-up was carried out on 6101 employees of the Italian Telecommunications Company (Telecom Italia) to study the role of work at Video Display Units (VDU) for the evolution of different types of myopia (mild, intermediate and pathologic). The refractive modifications of myopic VDU operators were further studied with regard to differences in time of use of VDU (daily hours and years spent working at a VDU). No statistically significant difference was found for refractive modifications, neither with regard to the type of myopia, nor to the daily hours and years spent working at a VDU. The results have indicated that the use of VDU is not responsible for a worsening of myopia.
