We have reported two cases of keratopathy in polyurethane workers that appear to be identical to those described by previous authors. We have been able to produce similar findings in the corneas of cats by exposing the eyes of anesthetized animals to the vapor of two of the amines used as catalysts in polyurethane manufacture. We were unable to reproduce these results with toluene diisocyanate. Therefore we support the previous suggestion that the amine catalysts are responsible for the distinctive keratopathy in polyurethane workers. We are unable to substantiate the claim that toluene diisocyanate is responsible for this phenomenon.
