- Humidity (%): 45-65
- Air changes (per hr):- Photoperiod (hrs dark / hrs light): 12/12
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The untreated eye was used as a comparator control.
- Amount / concentration applied:
- 100 mg
- Duration of treatment / exposure:
- 21 days
- Observation period (in vivo):
- up to 21 days
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- A 100mg aliquot of the test substance was introduced into the rlght eye of one animal by gently pulling away the lower lid from the eyeball to form a cup into which the test substance was placed. The Iids were then held shut for a few seconds to prevent loss of the test substance. The left eye remained untreated. This animal was dosed as a screen to assess the severity of irritant response. The response to treatment observed was considered not to be unacceptable and did not preclude the treatment of two additional animals, bringing the total to three.
One, twenty four, forty eight, and seventy two hours, seven, fourteen, and twenty one days after dosing the animals were observed under standard conditions and the treated eye examined macroscoptically for damage or irritation to the cornea, iris and conjunctivae' using the untreated eye as a comparator control.

- Irritant / corrosive response data:
- Well defined (scores of 2) to moderate (scores of 3) conjunctival irrltation, iris inflammation (score of 1) and areas of corneal opacity (severity score of 2) were apparent in the treated eye of all three anilmals within one hour of dosing. Both the opaque areas of the cornea and the conjunctivae were discoloured blue with the test substance. The sclera and iris also showed blue discolouration, possibly indicating a degree of local absorptlon of the substance.
Corneal opacity and iris inflammation were maintained durlng the first week following dosing. Conjunctival irritation showed some recovery in two animals within forty eight hours, slight reaction being observed at this time. No conjunctival irritatlon remained in any animal after seven days although responses in the cornea and iris remained at this time and one week later, fourteen days after dosing. BIue staining or discolouratlon of aII regions of the eye also remained.
Iris inflammatlon had disappeared within twenty one days of dosing but areas of corneal opaclty were maintained in the treated eye of all animals. At this time, blue colouration was observed in the areas of the cornea showing opaclty, the sclera and conjunctivae. Iridial staining observed earlier in the study showed some reduction in severity but was still present. - Other effects:
- Changes in body weight during the course of the study were not remarkable.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye)
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test substance has an irreversible effect on the eye.
- Executive summary:
In a GLP compliant eye irritation study, performed according to OECD guideline 405, the test substance (0.1g) was placed in the conjunctival sac of the right eye of three New Zealand White rabbits (RTC 1995). The eyes were examined for 21 days and a mean score was calculated for the observations made at 24, 48, and 72 hours. Scores of 1.5, 1.8, 1, and 2 were observed for conjunctival redness, conjunctival chemosis, iris inflammation, and corneal opacity, respectively. All these effects were fully reversible within 21 days, except for the cornea score.Therefore it was concluded that the test substance had an irreversible effect in the eye.
