[Corneal sensitivity in workers in contact with petroleum products]

Evaluation of the corneal sensitivity was carried out in 251 workers who have had a direct contact with petrol and its derivates and in 45 persons of a control group. It was established that the corneal sensitivity--especially in its central region--was distinctly lowered in persons employed in the department of asphalt oxidation and cleaning of sewages. This concerned particularly the workers with a long-lasting, many years service.
