- Irritant / corrosive response data:
- In the left treated eye of the first animal, slight to severe conjunctiva lesions were recorded between Day 1 and Day 13, iris lesions were noted from Day 2 up to Day 9 and moderate to marked corneal opacity was seen between Day 2 and Day 9.
Ocular lesions were associated with neovascularisation, lacrimation and whitish deposit from Day 2 until Day 9 at the latest. Myosis was seen on Days 4 to 6 and half-closed eyes on Day 6. Then moderate alopecia, followed by scabs around the treated eye was also recorded from Day 7 until Day 10.
In the left treated eye of the second male, slight to severe conjunctiva lesions were observed between Day 1 and Day 9, accompanied by iris lesions until Day 7 and slight to marked corneal opacity until Day 9. Ocular lesions were associated lacrimation and myosis on Days 2 and 3.
In the left treated eye of the third male, slight to severe conjunctiva lesions were observed between Day 1 and Day 15, with iris lesions until Day 13 and slight to severe corneal opacity until the end of the observation period. Neovascularization, lacrimation, whitish deposit and myosis were also noted between
Day 2 and Day 22.
Mean scores calculated for each animal over 24, 48 and 72 hours were as follows:
. chemosis: 2.0, 1.7 and 3.0,
. redness of the conjunctiva: 3.0, 2.7 and 3.0,
. iris lesions: 1.0, 1.0 and 1.0,
. corneal opacity: 3.0, 2.7 and 3.7. - Other effects:
- No unscheduled deaths occurred during the study and no clinical signs indicative of systemic toxicity were noted in any animals.
The body weight of the animals was unaffected by the test item treatment.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Under the experimental conditions of this study, the test item was severely irritant when administered by ocular route to rabbits.
- Executive summary:
The objective of this study was to evaluate the potential eye irritant properties of the test item following a single ocular administration to rabbits.
This study was based on the international guidelines (OECD Guideline No. 405 and Commission Regulation (EC) No. 440/2008 of 30 May 2008, part B.5) and was conducted in compliance with the principles of Good Laboratory Practice.
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 [2-4] for conjunctival edema (chemosis) and for conjunctival redness,[1-1.5]for iris lesions and[3-4]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 [2-4] for conjunctival redness, [1-1.5] for iris lesions and [1-3] for corneal opacity, the test item was administered in the left eye of a third animal.
The test item was administered in the conjunctival sac of the left eye. The right eye remained untreated and served as control.
A dosage-volume of 0.1 mL/animal was used.
For all animals, a local anesthetic was used prior to treatment and the animals were placed under systemic analgesia throughout the study.
Before the 24-hour scoring, both eye of two animals were rinsed with a sterile isotonic saline solution (0.9% NaCl). Each animal was observed at least once a day for mortality and clinical signs. Ocular reactions were recorded approximately 1, 24, 48 and 72 hours after the administration and then daily until the end of the observation period. 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 once a week until the end of the evaluation of ocular reactions.
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 and no clinical signs indicative of systemic toxicity were noted in any animals.
The body weight of the animals was unaffected by the test item treatment.
In the left treated eye of the first animal, slight to severe conjunctiva lesions were recorded between Day 1 and Day 13, iris lesions were noted from Day 2 up to Day 9 and moderate to marked corneal opacity was seen between Day 2 and Day 9.
Ocular lesions were associated with neovascularisation, lacrimation and whitish deposit from Day 2 until Day 9 at the latest. Myosis was seen on Days 4 to 6 and half-closed eyes on Day 6. Then moderate alopecia, followed by scabs around the treated eye was also recorded from Day 7 until Day 10.
In the left treated eye of the second male, slight to severe conjunctiva lesions were observed between Day 1 and Day 9, accompanied by iris lesions until Day 7 and slight to marked corneal opacity until Day 9. Ocular lesions were associated lacrimation and myosis on Days 2 an
In the left treated eye of the third male, slight to severe conjunctiva lesions were observed between Day 1 and Day 15, with iris lesions until Day 13 and slight to severe corneal opacity until the end of the observation period. Neovascularization, lacrimation, whitish deposit and myosis were also noted between Day 2 and Day 22.
Mean scores calculated for each animal over 24, 48 and 72 hours were as follows:
- chemosis: 2.0, 1.7 and 3.0,
- redness of the conjunctiva: 3.0, 2.7 and 3.0,
- iris lesions: 1.0, 1.0 and 1.0,
- corneal opacity: 3.0, 2.7 and 3.7.
Conclusion
Under the experimental conditions of this study, the test item was severely irritant when administered by ocular route to rabbits.
