Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Animals for this study were selected from a stock supply of healthy adult rabbits of the New Zealand White strain. They were in the weight range of 2.86 to 3.05 kg and 34 or 39 weeks of age, prior to treatment (Day 1). All rabbits were acclimatised to the experimental environment for a period of 8 to 15 weeks prior to the start of the study.
Each animal was housed individually in a plastic cage with perforated floors and was offered 125 g of a standard laboratory rabbit diet per day; drinking water was provided ad libitum. The batch of diet used for the study is analysed for nutrients, possible contaminants and micro-organisms likely to be present in the diet and which, if in excess of specified amounts, might have an undesirable effect on the test system. A dietary supplement of hay was offered during acclimatisation until two days prior to dose instillation, for the remainder of acclimatisation and throughout the study observation period wholemeal bread was offered.
During the acclimatisation and study period the animals were given small soft white untreated wood blocks for environmental enrichment.
Results of routine physical and chemical examination of drinking water, as conducted by the supplier are made available to Huntingdon Life Sciences. Animal room environmental controls were set to maintain temperature within the range 16 to 20°C, and relative humidity within 40 to 70%. These environmental parameters were recorded and the permanent record archived with other departmental raw data. Lighting was controlled by means of a time switch to give 12 hours of artificial light (06:00 to 18:00 GMT) in each 24 hour period.
Each animal was identified by a numbered tag placed through the edge of one ear. This identification was unique within the Department throughout the duration of the study. Each cage was identified by a coloured label displaying the study number and animal number.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The left eye remained untreated
- Amount / concentration applied:
- 0.1 mL
- Duration of treatment / exposure:
- Single ocular dose
- Observation period (in vivo):
- 1, 24, 48 and 72 hours and eight days after treatment
- Number of animals or in vitro replicates:
- Three
- Details on study design:
- Topical anaesthetics and systemic analgesia:
The following topical anaesthetic and systemic analgesia regime was employed:
60 minutes before administration: 0.01 mg/kg buprenorphine was administered subcutaneously.
15 minutes before administration topical anaesthesia was administered: one/two drops of topical ocular anaesthesia were applied to each eye; the procedure was repeated 5 minutes later. The test material was administered approximately 10 minutes after the last administration of anaesthesia.
Eight hours after test material administration: 0.01 mg/kg buprenorphine and 0.5 mg/kg meloxicam were administered subcutaneously.
Twenty-four hours after instillation of the test substance the second and third animalstreated received 0.5 mg/kg meloxicam administered subcutaneously.
Treatment Procedure:
The eyes of each animal were examined prior to instillation of the test substance to ensure that there was no pre-existing corneal damage, iridial inflammation or conjunctival irritation. Each animal was gently restrained. The dose was instilled into the right eye by pulling the lower eyelid away from the eye ball to form a cup into which the test substance was dropped. The eyelids were then gently held together for one second before releasing; the left eye
remained untreated.
A single animal (Number 90) was treated in advance; in the absence of a severe effect in this animal two further animals were committed to the study.
Serial Observations
Clinical Signs:
The behaviour of each rabbit was observed immediately following instillation of the test substance to allow assessment of the initial pain response. The animals were returned to their cages and checked at least twice during the first hour after dosing and at regular intervals throughout the day to ensure no severe injury passed unnoticed. Ocular reactions to treatment were assessed 1, 24, 48 and 72 hours and eight days after treatment.
Ocular Responses:
The untreated eye was used as a comparison with the treated eye during assessment of ocular lesions.
Termination:
Following completion of the observation period the animals were humanely killed by an intravenous injection of sodium pentobarbital.
The presence or absence of ulceration or necrosis was designated + (positive) or - (negative).
An opthalmoscope or pencil beam torch was available for use to facilitate inspection of the eyes.

- Ocular Responses
Injection of the conjunctival blood vessels and moderate discharge were evident in the sentinel animal one hour after instillation. Injection of the conjunctival blood vessels, very-slight chemosis and slight or moderate discharge were apparent in the remaining animals at this time; the conjunctival injection persisted throughout the first 24 hours after instillation in these animals. The treated eye of each animal was overtly normal 48 hours after instillation. Instillation of the test material gave rise to practically no initial pain response - Other effects:
- Clinical Signs
There was no sign of toxicity or ill health in any rabbit during the observation period.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The highest total mean score was 6.7 occurring at the one hour observation; accordingly under the criteria Kay and Calandra (1962) TM 09-0217 was classified as “minimally irritating” to the eye. TM 09-0217 did not require labelling in accordance with European Commission regulation 1272/2008.
- Executive summary:
The eye irritation potential of the test substance, TM 09-217, was assessed as not an eye irritant according to OECD Test Guideline 405 using an in vivo method.
