Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: expert judgment
- Conclusions:
- The test substance is not irritating to the eyes
- Executive summary:
In an in vivo test two rabbits were treated with the test substance (0.1 mL applied in the conjunctival sac of one eye) after systemic and local analgesia/anaesthesia . No signs of irritatiion except for very slight effects on the conjunctivae after 1, 24 and 48 hours became apparent. After 72 hours no effects were noted. Therefore it is concluded that the test substance is not irritating to the eyes.
