At 1 h post application, conjunctival redness (score 2) and chemosis (score 1) were noted in all animals. However, the effects were fully reversible within 24 h for chemosis and within 48 h for redness (see table 2). No effects on iris or cornea were observed during the study period. - Other effects:
- Body weight
All animals showed expected gain in body weight during the study (table 3).
