- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS
- Source: David Percival Ltd., Moston, Sandbach, Cheshire, U.K.
- Age at study initiation: Twelve to sixteen weeks old
- Weight at study initiation: 2.69 - 2.89 kg (3 animals: 2.70 kg, 2: 2.57 kg, and 2.57 kg, respectively)
- Housing: The animals were individually housed in suspended metal cages.
- Diet (ad libitum): Spillers Rabbit Diet, Dalgety Agriculture Ltd., Almondsbury, Bristol, U.K.)
- Water (ad libitum): Mains drinking water
- Acclimation period: Minimum acclimatisation period of five days
ENVIRONMENTAL CONDITIONS
- Temperature: 16 - 19 °C
- Relative humidity: 49 - 65%
- Air exchange: approximately 15 changes per hour
- Photoperiod (hrs dark / hrs light): 12/12
No further information on the test animals was stated.
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 material, which was found to weigh approximately 99 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 immediatley after application, to prevent loss of the test material, and then released. The left eye remained untreated and was used for control purpose.
No further information on the amount/concentration applied was stated. - Duration of treatment / exposure:
- Not applicable
- Observation period (in vivo):
- Immediately after administration of the test material, an assessment of the inital pain reaction was made.
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment. - Number of animals or in vitro replicates:
- 3 rabbits (1 male/2 females)
- Details on study design:
- One rabbit was initially treated. Initial pain reaction had been observed in this animal.
After consideration of the ocular responses produced in the first treated animal, two additional animals were treated. In order to minimise pain on instillation of the test material, one drop of local anaesthetic ("Ophthaine", 0.5% proxymetacaine hydrochloride, E.R. Squibb & Sons, Limited Hounslow, Middlesex, U.K.) was instilled into both eyes of these animals 1 -2 minutes before treatment.
SCORING SYSTEM: Draize scoring system
Any other adverse ocular effects were also noted.
TOOL USED TO ASSESS SCORE: Examination of the eye was facilitated by use of the light source from a standard ophthalmoscope.
OBSERVATIONS:
Immediately after administration of the test material, an assessment of the inital pain reaction was made.
No further information on the study design was stated.

- Irritant / corrosive response data:
- Initial pain reaction had been observed in the first treated animal.
Residual test material was noted around the treated eye of two animals one hour after treatment.
No corneal or iridial effects were noted during the study.
Minimal to moderate conjunctival irritation was noted in all treated eyes one hour after treatment. Minimal conjunctival redness persisted in one treated eye at the 24-hour observation.
Treated eyes appeared normal 24-48 hours after treatment.
