Irritant / corrosive response data:
Reversibility of any observed effect: Changes not fully reversible within 21 days
Other effects:
The test was conducted as follows:
4 seconds after instillation of the test article in the eyes of 3 rabbits the eyes were washed for 5 min with water.The results correspond to the results achieved without washing:
Cornea: in all animals turbation of cornea. In 2 animals vascularization.
Iris: in 2 animals inflamation of iris.
conjunctiva: in 2 animals diffuse highly red discolouration of the conj., also swelling.
The eyes were after 14 days free of syptoms.
Another test was conducted as follows:
30 seconds after instilation of the test article in the eyes of 3 rabbits the eyes were washed for 5 min with water.
the results correspond to the results achieved without washing:
Cornea: in all animals turbation of cornea.
Iris: in 2 animals inflamation of iris.
conjunctiva: in all animals diffuse highly red discolouration of the conj.,also swelling.
The eyes were after 7 days free of symptoms.
