[Effect of working conditions in a china-manufacturing plant on the eye].

629 workers of the China Plant "Lubiana" have been examined and divided into 4 groups varying with hazards affecting the sight organ. In groups I and II of those exposed to ceramic dusts and paints, approx. 80% exhibited coniogenic changes in the protective apparatus of the eye and cornea. In groups III and IV, with no permanent and direct exposure to the mentioned hazards, 40% exhibited nonspecific (for that type of ceramic plants) chronic inflammation of the conjunctivae and eyelid margins.
