Test system
- Vehicle:
- not specified
- Controls:
- not specified
- Amount / concentration applied:
- 0.1 ML
- Observation period (in vivo):
- Assessment of occular damage/irritation was made approximatley 1 hour, 24,48 and 72 hours following treatment. Any other occular effects were also noted. Examination of the eye was facilitated by the use of a light source from a standard opthalmoscope.
An additional observation was made in one treated eye on Day 7 to assess the reversibility of the occular effects. - Number of animals or in vitro replicates:
- 3
- Details on study design:
- Initially, a single rabbit was treated. A volume of 0.1 ml of the test material 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 treatment, to prevent loss of the test material, and then released. The left eye remained untreated and was used for control purposes. Immediatley after administration of the test material, an assessment of the initial pain reaction was made.
After consideration of the ocular responses produced in the first treated animal , two additional animals were treated. In order to minimise pain on application of the test material , one drop of local anaethetic was instilled into both eyes of the final animal 1 to 2 minutes before treatment.

Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified in accordance with EU criteria
- Conclusions:
- The test material produced a maximum group mean score of 9.0 and was classified as a mild irritant (Class 4 on a 1-8 scale) to the rabbit eye according to a modified Kay and Calandra classification system.
- Executive summary:
A GLP study in accordance with OECD guideline 405 was performed in order to assess the irritancy potential of Inhibitor AHM P500 to the eye of the New Zealand White Rabbit.
A single application of the test material to the non-irrigated eye of three rabbits produced scattered or diffuse corneal capacity, iridial inflammation and minimal conjunctival irritation. One treated eye appeared normal at the 48 hour observation, one treated eye appeared normal at the 72 hour observation and the remaining treated eye appeared normal at the 7 day observation.
The test material produced a maximum group mean score of 9.0 and was classified as a mild irritant (Class 4 on a 1-8 scale) to the rabbit eye according to a modified Kay and Calandra classification system.
