    Area of Science:

    • Occupational Health
    • Ophthalmology
    • Toxicology

    Background:

    • Styrene exposure in industrial settings may pose risks to ocular health.
    • Previous reports suggest potential links between styrene and severe ocular conditions like retrobulbar neuritis and central retinal vein occlusion.

    Purpose of the Study:

    • To assess the ocular toxicity of styrene in a cohort of chemical plant workers.
    • To investigate the prevalence of specific ocular conditions previously associated with styrene exposure.

    Main Methods:

    • Conducted medical histories and comprehensive ocular examinations.
    • Evaluated 345 workers employed in a styrene production facility.
    • Correlated ocular findings with the intensity of styrene exposure.

    Main Results:

    • No cases of retrobulbar neuritis or central retinal vein occlusion were identified in the studied workers.
    • Conjunctival irritation was observed in 22% of workers.
    • The incidence of conjunctival irritation showed a positive correlation with the intensity of styrene exposure.

    Conclusions:

    • The study did not find evidence of severe ocular toxicity, such as retrobulbar neuritis or central retinal vein occlusion, in workers exposed to styrene.
    • Conjunctival irritation is a confirmed ocular effect of styrene exposure, consistent with prior research.
    • Occupational health surveillance for styrene-exposed workers should consider monitoring for irritant effects.
