Ricin ocular

In animal studies, low ricin concentrations caused irritation and the development of conjunctivitis. In ocular exposure, pseudomembranous conjunctivitis occurred following... 

As with other protein toxin weapons, we expect that the generation of primary or secondary ricin aerosols, especially within an enclosed space, poses a potential biological warfare or bioterrorism risk (LeClaire and Pitt, 2005 Millard, 2005). Due to the technical challenges of generating highly toxic and persistent protein aerosols, we expect the risk of lethality to be less than the risk of operational disruption, prolonged incapacitation from ocular or respiratory tract inflammation, and increased burden on medical and logistical assets. 

For accidental ocular exposure to ricin, extensive rinsing with 10% lactose solution may reduce toxicity if performed immediately after exposure (Strocchi et al., 2005).
