- Executive summary:
The objective of this study was to assess the ocular irritation potential of the test substance following OECD Guideline 405. The initial test, with 0.1 mL of test substance (equivalent to 26.51 mg enzyme concentrate dry matter/mL or 15.64 mg active enzyme protein/mL). applied to the left eye and the right eye as control, was conducted on one rabbit. After 24 hours, fluorescein was instilled and rinsed with 0.9% NaCl. The eye was examined with a UV light to detect corneal damage. The eye was also examined at 48 and 72 hours. Changes in the eye were graded according to a numerical scale 1, 24, 48, and72 hours after treatment. The confirmatory tests were carried out on an additional 2 rabbits and the tests and examinations were performed in a similar manner.
No clinical signs were observed in the animals during the daily observations. The mean values for all three rabbits were 0 for cornea opacity, iris lesion, chemosis of conjunctiva, and redness of conjunctiva.
