Changes in the anterior segment of the eye in workers employed in the manufacture of coke

Abstract

Provedeno ispitivanje u odnosu na očne smetnje u radnika u proizvodnji koksa pokazalo je u visokom postotku promjene prednjeg segmenta oka. Registrirani simptomi hiperemije konjunktive, pingvekula, pigmentacije i konjunktivitisa najvjerojatnije su vezani za specifičan rad i izloženost ugljenoj prašini i neugodnim nadražljivcima. U radnika s manje od dvije godine ekspozicije nema promjena u sekreciji suza, u onih koji rade između 2 - 7 godina dominira hipersekrecija, a nakon duže izloženosti dolazi u većini izloženih radnika do hiposekrecije.An investigation carried out of eye disorders in workers employed in the manufacture of coke demonstrated a high percentage of changes in the anterior segment of the eye. Registered symptoms such as conjunctival hyperemia, pinguecula, pigmentation and conjuctivitis were most probably connected with specific work and exposure to coal dust and irritants. In workers exposed for less than two years there were no changes in lacrimal secretion. In those working for 2 - 7 years excessive hypersecretion dominated, and after a longer period of exposure the majority of workers had hyposecretion
