- Animal Information
Two New Zealand White (Hsdlf:NZW) strain rabbits were supplied by Envigo RMS (UK) Limited, Leicestershire, UK. At the start of the study the animals weighed 2.94 or 4.40 kg and were 12 to 52 weeks old. After an acclimatization period of at least 5 days each animal was given a number unique within the study which was written with a black indelible marker-pen on the inner surface of the ear and on the cage label.
Animal Care and Husbandry
The animals were individually housed in suspended cages. Free access to mains drinking water and food (2930C Teklad Global Rabbit diet supplied by Envigo RMS (UK) Limited, Oxon, UK) was allowed throughout the study. The diet and drinking water were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
ENVIRONMENTAL CONDITIONS
The temperature and relative humidity were set to achieve limits of 17 to 23 °C and 30 to 70% respectively. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
The 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.

- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent negative control
- Amount / concentration applied:
- A volume of 0.1 mL of the test item was placed into the conjunctival sac of the right eye.
- Duration of treatment / exposure:

- Details on study design:
- 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.
Initially, a single rabbit was treated. A subcutaneous injection of buprenorphine 0.01 mg/kg was administered 60 minutes prior to test item application to provide a therapeutic level of systemic analgesia. Five minutes prior to test item application, a pre-dose anesthesia of ocular anesthetic (two drops of 0.5% tetracaine hydrochloride) was applied to each eye.
A volume of 0.1 mL of the test item 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. Immediately after administration of the test item, an assessment of the initial pain reaction was made according to the six point scale - Initial Pain Reaction, please see "Any other information on materials and methods, inc. tables" for further information.
Eight hours after test item application, a subcutaneous injection of post-dose analgesia, buprenorphine 0.01 mg/kg and meloxicam 0.5 mg/kg, was administered to provide a continued therapeutic level of systemic analgesia. The treated animal was checked for signs of pain and suffering approximately 12 hours later. No further analgesia was required.
After consideration of the ocular responses produced in the first treated animal, a second animal was similarly treated.
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the numerical evaluation (Draize, J.H, 1977) given below.
Any other ocular effects were also noted. Examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.
Any clinical signs of toxicity, if present, were also recorded.
An additional observation was made on Day 7 to assess the reversibility of the ocular effects.
Individual body weights were recorded on Day 0 (the day of dosing) and at the end of the observation period.
