||Chronic conjunctivitis in arc welders - Cross-sectional study

||A follow-up study of chronic conjunctivitis in arc welders in a foundry in Italy was conducted from 1979 up to 1989. Airborne dust concentrations in the foundry often exceeded the TLV-TWA limit. The frequency of chronic conjunctivitis was markedly higher amongst the welders than in the unexposed controls (RR = 4.25). The incidence rate of conjunctivitis was 4.98% in the exposed group: manual welders showed a higher incidence rate (5.69%) than non-manual welders (risk ratio = 1.76). Ocular symptoms (eye burning, lacrymation, photophobia) often occurred well before the development of chronic conjunctivitis (predictive value = 61.5%). In current occupational health practice, the disclosure of a high prevalence of ocular symptoms should lead to careful examination of the working environment.
