Prediction of ocular irritancy potential from dermal irritation test results

In a survey of the test files of Haskell Laboratory, it was found that of the materials that had been tested on rabbit skin for primary irritation or corrosivity, 60 were severe irritants or corrosive on the skin and had also been tested for ocular irritancy. Of these 60 materials only 39 were severe eye irritants, while 15 were mild irritants or non-irritants and the remainder were considered to be moderate irritants. Thus, to suggest that materials are eye irritants solely on the basis of their skin-irritation properties may be misleading, even when severe dermal irritants are considered.
