Test animals / tissue source

Species:
rabbit
Strain:
Himalayan
Details on test animals or tissues and environmental conditions:
The test was performed on 3 male and 3 female rabbits of the Himalayan breed weighing 1.5 to 2 kg The animals were housed individually in metal cages, were kept at a constant room temperature of 18 ± 10 °C, at a relative humidity of ± 5 % and on a 14 hour light cycle day. The animals had ad libitum access to standard rabbit food - NAFAG, Gossau SG - and water. Prior to treatment they were adapted to our laboratories for a minimum of 8 days. Only rabbits with normal ophthalmic findings were used for these tests.

Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: The right eye was not treated and served as an untreated control.
Amount / concentration applied:
0.1 g of the test substance was inserted into the conjunctival sac of the left eye of the 6 rabbits.
Duration of treatment / exposure:
7 days
Observation period (in vivo):
1,2,3,4,7 days after the application
Number of animals or in vitro replicates:
3 male and 3 famale
Details on study design:
The test material in an amount of 0.1 g was inserted into the conjunctival sac of the left eye of the 6 rabbits and the lids were gently closed for one second. The right eye was not treated and served as an untreated control. In 3 of the 6 rabbits approximately 30 seconds after treatment the treated eye was flushed with 10 ml of lukewarm water The eye irritation was appraised with a slit - lamp on day 1, 2, 3, 4 and 7 and was scored for each individual rabbit.

Any other information on results incl. tables

The primary eye irritation index represents the sum of the mean values for cornea, iris and conjunctivae. this procedure was carried out separately for unrinsed and rinsed eyes respectively.
