Allergic conjunctivitis had a prevalence rate of 9.2% among all the workers studied. The prevalence rate was 9.8% and 6.7% in technical and administrative workers, respectively. This may be attributed to the higher exposure to sawdust among the technical workers. However, the difference was not significant. Previously, Omoti et al. (21) reported a high prevalence rate of
23.3% among the industrial workers they studied. This may have resulted from differences in the nature of irritants in these industries. Some wood species, such as Triplochiton scleroxylon and Nauclea diderrichii, milled in Nigeria are highly allergenic (22). The rubbing of the eyes during itching with hands that are likely not clean due to the working environment may have rendered the technical workers more prone to develop bacterial conjunctivitis.
