Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Animals
Healthy New Zealand White rabbits were used. These were aged 12-14 weeks with average body weights of 2.19 kgs (2 females) and 2.15 kgs. (2 males) and were obtained from a commercial supplier (Hacking and Churchill). Six rabbits (3 males and 3 females) were acclimatized in the test area for one week prior to the start of the trial.
Husbandry
The rabbits were caged singly in an experimental room maintained at a temperature of l6°C (± 1°)and a relative humidity of 50 - 70%. Animals were exposed to artificial light for 10 hours daily from 08.00 - 18.00 hours. A commercial diet (Labsure, Christopher Hill. Group)was fed ad lib. Filtered water acidified to approximately pH3 was available at all times.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other:
- Amount / concentration applied:
- 0.1 ml of the test compound were instilled into the conjunctival sac of the left eye.
- Duration of treatment / exposure:
- 30 seconds
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- Six rabbits
- Details on study design:
- The eyes of the experimental animals were examined and found normal prior to the test. 0.1 ml of the test compound were instilled into the conjunctival sac of the left eye. The eyelids were then held closed for 1 second. The right eye served as a control. After 30 seconds the compound was, as far as possible, flushed out of the eyes of three of the rabbits with approximately 200 ml. of warm water.
The rabbits were examined 1, 24, 48 and 72 hours after application of the test compound and for any further period that was considered necessary. The ocular reactions were scored by the method described in "Appraisal of the Safety of Chemicals in Food Drugs and Cosmetics" page 51, published by the Association of Food and Drug Officials of the U.S.A. Fluorescein (Fluorets -Smith and Nephew Pharmaceuticals Limited)was used as an aid in assessing corneal damage.

A very slight reaction was seen 2/3 washed and 3/3 unwashed eyes in 1 hour after compound application.
3/3 washed and 1/3 unwashed eyes were normal at 24 hours. The remaining 2/3 unwashed eyes were normal at 48 hours.
The reactions seen in unwashed eyes were similar to those in washed eyes. - Other effects:
- None
