Toxic effects on eyes result from exposure to pesticides via inhalation, 
ingestion, dermal contact and ocular exposure. Exposure of unprotected eyes to 
pesticides results in the absorption in ocular tissue and potential ocular 
toxicity. Recent literature on the risks of ocular toxicity from pesticide 
exposure is limited.Ocular toxicity from pesticide exposure, including the 
dose-response relationship, has been studied in different animal species. 
Cholinesterase enzymes have been detected in animal ocular tissue, with evidence 
of organophosphate-induced inhibition. Pathological effects of pesticides have 
been observed in conjunctiva, cornea, lens, retina and the optic nerve. 
Pesticide exposure has been associated with retinopathy in agricultural workers 
and wives of farmers who used pesticides. Saku disease, an optico-autonomic 
peripheral neuropathy, has been described in Japan in people living in an area 
where organophosphates were used. Pesticide exposure is also associated with 
abnormal ocular movements.Progressive toxic ocular effects leading to defective 
vision are a serious health concern. Agricultural workers are at high risk of 
exposure to pesticides and associated ocular toxicity. Primary prevention is the 
appropriate method of protecting eyes from pesticide-related damage. This 
includes improved eye safety and care in workplaces, and effective pesticide 
regulation for maintenance of public eye health.
