- Irritant / corrosive response data:
- Conjunctival redness (score 2) was observed in 3/3 animals 1 h after instillation. The redness persisted in 3/3 animals (score 1) until the 48 h reading time point. Chemosis (score 1-2) was observed in 3/3 animals and iridial irritation (score 1) was seen in 2/3 animals at the 1 h reading time point. Both effects had cleared completely by the 24 h reading. All effects were completely reversible within 72 h.
Remains of the test substance were noted in the treated eye of 3/3 animals on Day 1, while remains were present on the outside of the eyelids on Day 2 in 1/3 animals. - Other effects:
- There was no mortality, no clinical signs were observed and the body weight was within the normal range during the study period.
