Applicant's summary and conclusion
- Interpretation of results:
- other: severely irritant
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- The test item was severely irritant when administered by ocular route to rabbits.
In addition, the effects on the conjunctiva were not fully reversible within 21 days of application in one animal; it was considered that the test item caused serious eye damage.
According to the criteria of CLP Regulation, the test item should be classified category 1 and assigned the signal word "danger" and the hazard statement "H318: causes serious eye damage". - Executive summary:
The objective of this study was to evaluate the potential irritant properties of the test item for the eye following a single administration to rabbits.
This study was conducted in compliance with OECD Guideline No. 405 and the principles of Good Laboratory Practices.
Methods
The test item was first administered to a single male New Zealand White rabbit.
As mean value from grading at 24, 48 and 72 hours after instillation was = 2 for conjunctival edema (chemosis) and for conjunctival redness and = 1 for iris lesions and for corneal opacity, the test item was administered in the left eye of a second animal.
After administration to the second animal, as mean value from grading at 24, 48 and 72 hours after instillation was = 2 for conjunctival redness and = 1 for corneal opacity, no other animal was treated.
The test item was administered inthe conjunctival sac of the left eye. The right eye remained untreated and served as control.
A quantity of 0.1 g/animal was used.
For the first and second animals, a local anesthetic was used before the 24-hour reading and prior to treatment, respectively.
Just after the 1-hour scoring, both eyes were rinsed with a sterile isotonic saline solution (0.9% NaCl).
Due to important ocular reactions in both animals and in order to perform ocular reactions evaluation in good conditions, eyes were rinsed again before the 24-hour reading with sterile isotonic saline solution (0.9% NaCl).
Each animal was observed at least once a day for mortality and clinical signs. Ocular reactions were observed approximately 1 hour, 24, 48 and 72 hours after the administration and then daily until the reversibility of the ocular reactions or until day 21. The mean values of the scores for chemosis, redness of the conjunctiva, iris lesions and corneal opacity were calculated for each animal. Body weight was recorded on the day of treatment and at the end of the evaluation of ocular reactions or the day after the end of the evaluation of ocular reaction.
On completion of the observation period, the animals were sacrificed then discarded without macroscopic post-mortem examination.
Results
No unscheduled deaths occurred during the study.
One animal showed loud breathing on day 2. This could be considered as pain resulting from severity of ocular lesions. Thereafter chromorhynorrhea probably due to repeated administrations offluorescein solutionswas noted from day 15.
However no clinical signs indicative of systemic toxicity were observed in any animals. The body weight of the animals was unaffected by the test item treatment.
In the left treated eye of one animal, marked to severe chemosis and severe redness of the conjonctiva were observed from day 1 to day 4. Severe redness persisted on day 5. Slight to moderate conjunctiva reactions were noted between days 6 and 11. Thereafter, moderate to marked chemosis was recorded between days 12 and 19, whereas moderate to severe redness was observed from day 12 to day 16. Then, slight conjunctiva reactions persisted until the end of the observation period (day 21).
Iris lesions were noted from day 1 to day 19.
Moderate to marked corneal opacity was observed on days 2 and 3. Then, slight corneal opacity was recorded between days 4 and 14. Corneal opacity was graded marked again from day 15 to day 18.
In addition, marked blepharospasm was noted on day 2 and neovascularization was recorded from day 8 to day 18.
In the left treated eye of one animal, moderate chemosis and moderate to severe redness of the conjonctiva were noted from day 1 to day 3. Then, slight to moderate conjonctiva reactions persisted until day 9.
Iris lesions were noted from day 1 to day 3.
Moderate to marked corneal opacity was recorded from day 2 to day 4. Thereafter, slight corneal opacity was still present until day 7.
Lacrimation and whitish deposit were noted in the left eye of both animals on many occasions during the observation period.
Mean scores calculated for each animal over 24, 48 and 72 hours were as follows:
. chemosis: 3.3 and 1.7 ; showing eye irritation in 1/2 animals,
. redness of the conjunctiva: 3.0 and 2.7; showing eye irritation in 2/2 animals,
. iris lesions: 1.0 and 0.7 ; showing eye irritation in 1/2 animals,
. corneal opacity: 2.0 and 2.7; showing eye irritation in 2/2 animals.
However, as the effects on the conjunctiva were not fully reversible within 21 days of application in one animal; it was considered that the test item caused serious eye damage.
Conclusion
Under the experimental conditions of this study, the test item was severely irritant when administered by ocular route to rabbits.
In addition, the effects on the conjunctiva were not fully reversible within 21 days of application in one animal; it was considered that the test item caused serious eye damage.
According to the criteria of CLP Regulation,the test item should be classified category 1 and assigned the signal word "danger" and the hazard statement "H318: causes serious eye damage".
