Irritant / corrosive response data:
Only very slight conjunctival reactions, including very slight chemosis (grade 1), very slight redness of the conjunctiva (grade 1) and clear discharge, were observed in all animals on day 1.
No other ocular reactions were observed during the study. Mean scores calculated for each animal over 24, 48 and 72 hours were 0.0, 0.0 and 0.0 for chemosis, redness of the conjunctiva, iris lesions and corneal opacity.
