Test system
- Vehicle:
- unchanged (no vehicle)
- Amount / concentration applied:
- 0.1 ml per eye
- Duration of treatment / exposure:
- 24h
- Observation period (in vivo):
- 72h
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- About 24 hours before the start of the study the test eyes of all animals were examined under UV light for corneal lesions after instillation of one drop of a 0.01 % fluorescein-sodium solution. Only animals without ocular abnormalities were used for the study.
0.1 ml Isodecylethernitril was applied once to the conjunctival sac of the left eye of three rabbits. The untreated eyes served in each case as a control.
24 hours after application and at all other designated examination times at which the treated eyes still showed discharge or at which a corneal examination with fluorescein sodium solution took place, the treated eyes were washed out thoroughly with isotonic saline at approx. 37°C.
The eyes were examined 1, 24, 48 and 72 hours after application of the test substance. At 24 and 72 hours the eyes were also examined for cornealiesions under UV light after instillation of one drop of 0.01 % fluorescein-sodium solution. Lesions in comea, iris or conjunctivae were graded numerically.

- Irritant / corrosive response data:
- One hour after application the conjunctivae the animals showed a diffuse crimson red up to a diffuse beefy red colour and very slight swellings. Additionally, clear·colourless eye discharge was noted. 24 hours after application a diffuse crimson colour of the cunjuntivae were observed in two anima/so 48 hours after application all signs of irritation were reversible.
Based on the individual scores after 24, 48 and 72 hours, the following mean values
were calculated:
