- Irritant / corrosive response data:
- - Slight conjunctival redness (grade 1) was observed in one animal 1 hour after application up to 24 hours. Two animals showed moderate conjunctival redness (grade 2) from 1 hour until 48 hours after application. Slight conjunctival chemosis (grade 1) was noted in one animal 24 hours after application only. Slight discharge (grade 1) was observed in two animals 1 hour after application. Severe discharge (grade 3), noted in one animal after 1 hour, decreased to slight at the 24 hour-reading.
- No other ocular reactions were observed during the study.
- The ocular reactions were reversible in one animal within 48 hours and in two animals within 72 hours after application.
- Mean scores calculated for each animal over 24, 48 and 72 hours were 0.0 for corneal opacity and for iris lesions, 0.3, 1.3 and 1.3 for redness of the conjunctiva and 0.0, 0.3 and 0.0 for chemosis.
