Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS - New Zealand White (Hsdlf:NZW) strain rabbits- Source: Harlan Laboratories UK Ltd., Leicestershire, UK- Age at study initiation: twelve to twenty weeks old- Weight at study initiation: 2.69 or 3.10 kg- Housing: the animals were individually housed in suspended cages.- Diet (ad libitum): 2930C Teklad Global Certified Rabbit diet supplied by Harlan Laboratories UK Ltd., Oxon, UK- Water (ad libitum): mains drinking water- Acclimation period: at least five daysThe animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.ENVIRONMENTAL CONDITIONS- Temperature: 17 to 23°C- Relative humidity: 30 to 70%- Air exchange: at least fifteen changes per hour- Photoperiod (hrs dark / hrs light): 12/12
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL- Amount(s) applied (volume or weight with unit): a volume of 0.1 ml of the test item, which was found to weigh approximately 96 mg (as measured by gently compacting the required volume into an adapted syringe) was placed into the conjunctival sac of the right eye, formed by gently pulling the lower lid away from the eyeball. The upper and lower eyelids were held together for about one second immediately after treatment, to prevent loss of the test item, and then released. The left eye remained untreated and was used for control purposes.
- Duration of treatment / exposure:
- not applicable
- Observation period (in vivo):
- approximately 1 hour and 24, 48 and 72 hours following treatment as well as on days 7 and 14
- Number of animals or in vitro replicates:
- 2 male rabbits
- Details on study design:
- Immediately before the start of the test, both eyes of the provisionally selected test rabbits were examined for evidence of ocular irritation or defect with the aid of a light source from a standard ophthalmoscope. Only animals free of ocular damage were used.INITIAL AND CONFIRMATORY TESTInitially, a single rabbit was treated. Immediately after administration of the test item, an assessment of the initial pain reaction was made according to the six point scale (please refer to table 2 in the field "Any other information on materials and methods incl. tables" below).After consideration of the ocular responses produced in the first treated animal, a second animal was treated.SCORING SYSTEM: according to the Draize scaleAny other ocular effects were also noted.Any clinical signs of toxicity, if present, were also recorded.Individual bodyweights were recorded on Day 0 (the day of dosing) and at the end of the observation period.If evidence of irreversible ocular damage is noted, the test item will be classified as corrosive to the eye.TOOL USED TO ASSESS SCORE: examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.
