No data

Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: The right eye remained untreated and served as the control.
Amount / concentration applied:
undiluted: Amount applied: 0.1 ml
Duration of treatment / exposure:
No data
Observation period (in vivo):
Eyes were examined at 1, 24, 48 and 72 hours after treatement. After recording the observations at 24 hours, the eyes of all rabbits were examined with the aid of fluorescein to further characterise corneal opacity.

Time point:
other: 1 hr
Score:

Max. score:
3
Reversibility:
fully reversible within: 48 hr
Irritant / corrosive response data:
Corneal opacity : No corneal opacity was observed in any of the treated eyes at any of the observation periods. Iris : the iris response was normal in all treated eyes.Conjunctivae : slight conjunctival redness and chemosis were observed in all three treated eyes at the 1-hour observation point (grading score of 1). Conjunctival redness and chemosis persisted in 2 of 3 animals for 24 hours and was resolved by the 48 hour time point. In the third animal, all signs of irritation were resolved by the 24-hour observation point.
Other effects:
All of the animals exhibited an increase of body weight during the course of the study.

Any other information on results incl. tables

No overt sign of toxicity other than the ocular effects was evident during the course of the study in any of the animals.

No fluorescein staining was observed in any of the treated eyes at all observation points.
