Any other information on results incl. tables
There was no sign of toxicity or ill health in any rabbit during the observation period.
A crimson-red conjunctival appearance with very-slight chemosis and, in one case, slight discharge, was evident in all animals one hour after instillation. In two animals injection of the conjunctival blood vessels persisted 24 or 48 hours after instillation after which the eyes were overtly normal. In the remaining animal a beefy-red conjunctival appearance with very slight chemosis, scattered or diffuse areas of opacity covering up to a quarter of the corneal surface and iritis were apparent 24 hours after instillation. The opacity, iritis and chemosis resolved within the next 24 hours by when a crimson-red conjunctival appearance was evident. Injection of the conjunctival blood vessels was apparent 72 hours after instillation, resolving by Day 8. The treated eye of all animals was overtly normal by Day 8. Instillation of the test substance gave rise to a moderate initial pain response in the sentinel animal; subsequent animals were treated with local (ocular) anaesthesia prior to instillation.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The highest total mean score was 7.3 occurring at the 24-hour observation; accordingly under the criteria Kay and Calandra (1962) T-1620L was classified as “minimally irritating” to the eye. T-1620L did not require labelling in accordance with European Commission regulation 1272/2008.
