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.
