DESCRIPTION OF LESIONS:
Cornea1 opacity (grade 1) was observed in all three animals at the examination time points one hour to 5 days after instillation, in animal no. 3 until 6 days after instillation. All animals showed an irritation of the iris (grade 2) one hour after instillation, and an irritation (grade 1) 24 to 5 days in all animals, in animal no. 3 up to 6 days after instillation. Conjunctival redness of grade 1 was observed in all animals 1 to 24 hours after instillation, in animal no. 1 up to 5 days after instillation. Conjunctival chemosis (grade 1) was observed in all animals 1 to 24 hours after instillation, in animal no. 1 up to 72 hours after instillation. The fluorescein test performed after 24 hours revealed corneal staining in animal nos. 1 and 3 (1/2 of the corneal surface) and in animal no. 2 (1/4 of the corneal surface).
REVERSIBILITY: day 7 all scores at 0 - Other effects:
- There were no systemic intolerance reactions.

DESCRIPTION OF LESIONS:
Cornea1 opacity (grade 1) was observed in all three animals at the examination
time points one hour to 5 days after instillation, in animal no. 3 until 6
days after instillation. All animals showed an irritation of the iris
(grade 2) one hour after instillation, and an irritation (grade 1) 24 to 5
days in all animals, in animal no. 3 up to 6 days after instillation.
Conjunctival redness of grade 1 was observed in all animals 1 to 24 hours
after instillation, in animal no. 1 up to 5 days after instillation.
Conjunctival chemosis (grade 1) was observed in all animals 1 to 24 hours
after instillation, in animal no. 1 up to 72 hours after instillation. The
fluorescein test performed after 24 hours revealed corneal staining in
animal nos. 1 and 3 (1/2 of the corneal surface) and in animal no. 2 (1/4
of the corneal surface).
