The eye irritant effect of the test substance was investigated according to the method OECD Guideline 405. Three female albino rabbits were used in the study. Initially, one animal was exposed to 0.1 mL of the test substance in the left eye. The right eye remained untreated and served as control. Both eyes of all animals were examined and the changes were graded according to a numerical scale 1, 24, 48, and 72 hours after treatment.
No clinical signs were observed in the animals during the daily observations. At the examination 1 hour after exposure, conjunctiva appeared red (some blood vessels were definitely hyperaemic – equal to score 1) in the initial animals. The reaction persisted the following day (24 hours after exposure). However, it was considered ethically acceptable to proceed with two additional animals as only very mild reactions had been observed in the initial animal. Similar scoring of conjunctival redness was observed in the two additional animals at the examination 1 hour after exposure. At all examinations, all animals appeared normal. Mean values, based on the results from the 24, 48, and 72 hour readings were calculated. The mean values were 0.0, 0.0, 0.0, and 0.1 for cornea opacity, iris lesion, chemosis of conjunctiva, and redness of conjunctiva, respectively.
