Results and discussion
In vivo
Results
- Irritation parameter:
- overall irritation score
- Basis:
- mean
- Time point:
- other: 1 hour
- Score:
- 6
- Max. score:
- 110
- Reversibility:
- fully reversible within: 24 h
- Remarks on result:
- other: slight redness, and moderately increased discharge excretion
- Irritant / corrosive response data:
- One our after treatment some blood vessels hyperaemic occured in every animal. In all cases the discharge with moistening of the lids and hairs just adjacent to lids was found. Chemosis, corneal and iris alterations were not found during the study.
One our after the treatment the obseved highest irritation index was 6.
24 hours after the treatment primary irritation symptoms were not found in the treated animals.
48 and 72 hours after the treatment every animals was symptom-free.
72 hours after the treatment the study was terminated, since no primary irritation symptoms occured. - Other effects:
- The general state and behaviour of animals were normal during the whole study.
Chemosis, corneal, and iris alterations were not found during the study.
Applicant's summary and conclusion
- Interpretation of results:
- slightly irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In conclusion the test item applied to the rabbits's eye mucosa proved to be slightly irritant according to the irritation index.
The observed symptoms can be evaluated as fully reversible alterations.
