- Number of animals or in vitro replicates:
- In vitro - 3 eyes and 2 control eyes.
- Details on study design:
- It is a legal and ethical duty under the Animals (Scientific Procedure) Act 1986 that in the interest of animal welfare, the unnecessary use of animals is avoided, and that any testing which is likely to produce severe responses in animals is minimised.
Available information indicated that the test material had the potential to produce severe effects in a rabbit eye and to confirm this initial assessment, a Rabbit Enucleated Eye Test was performed.
A study was performed to assess the ocular irritancy potential of the test material in the rabbit following application onto the cornea of the enucleated eye. The assay has undergone inter-laboratory validation and has been shown to reliably detect test materials that are negligible, or moderate to severe ocular irritants.
The New Zealand White strain rabbit used in these laboratories has been shown to produce satisfactory responses using known ocular-irritants and non-ocular irritants during in-house validation. The results of the study are believed to be of value in predicting the ocular irritancy potential of the test material in man.

Any other information on results incl. tables
Moderate loss of transparency was noted in all test eyes during the study.
Corneal swelling of the test eyes was considerably greater than that observed in the control eyes over the same period.
Pitting and sloughing of the corneal epithelium was noted in all test eyes during the study.
Moderate fluorescein uptake was noted in the test eyes 240 minutes following test material applicaiton. No fluorescein uptake was noted in the control eyes 240 minutes following treatment.
