The treated eyes were not rinsed after application.
SCORING SYSTEM:
Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion.
TOOL USED TO ASSESS SCORE:
Eye examinations made with a Varta Cliptrix diagnostic-lamp.

Hypermeric blood vessels of the conjunctivae and nictitating membranes to diffuse conjunctival blood vessels were noted in all animals at the 1 hour reading and disappeared 24 hours after treatment (1 animal) or diminished to be clear at 48 hours (2 animals). Slight swelling of the conjunctivae and nictitating membrane was observed in two animals at the 1 hour reading and disappeared 24 hours later. The sclera was slightly to markedly reddened in all animals at the 1 hour reading and persisted with less severity in only one animal at 24 hours before disappearing at 48 hours.
The mean values from 24 to 72 hours (criteria for evaluation according the EEC Commission Directive 93/21/EEC) were 0 for corneal opacity, 0 for iris lesions, 0.3 for redness of the conjunctivae and 0 for chemosis of the conjunctivae.
All eye reactions were clear within 72 hours after treatment.
COLORATION:
No staining of the treated eyes by the test item was observed.
CORROSION:
No corrosion was observed at any of the measuring intervals. - Other effects:
- No clinical signs of systemic toxicity were observed in the anilmals during the study and no mortality occured.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based upon the criteria stated in EEC Commission Directive 93/21/EEC, classification of CA 2814 B (Intermediate of CGA 276854) is not required.
- Executive summary:
The primary eye irritation potential of CA 2814 B (Intermediate of 276854) was investigated by instillation of 0.1 ml into one eye of three young adult New Zealand White rabbits. The treated eyes were not rinsed after application. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion.
Hypermeric blood vessels of the conjunctivae and nictitating membranes to diffuse conjunctival blood vessels were noted in all animals at the 1 hour reading and disappeared 24 hours after treatment (1 animal) or diminished to be clear at 48 hours (2 animals). Slight swelling of the conjunctivae and nictitating membrane was observed in two animals at the 1 hour reading and disappeared 24 hours later. The sclera was slightly to markedly reddened in all animals at the 1 hour reading and persisted with less severity in only one animal at 24 hours before disappearing at 48 hours.
The mean values from 24 to 72 hours (criteria for evaluation according the EEC Commission Directive 93/21/EEC) were 0 for corneal opacity, 0 for iris lesions, 0.3 for redness of the conjunctivae and 0 for chemosis of the conjunctivae.
All eye reactions were clear within 72 hours after treatment.
No staining of the treated eyes by the test item was observed.
No corrosion was observed at any of the measuring intervals.
Based upon the criteria stated in EEC Commission Directive 93/21/EEC, classification of CA 2814 B (Intermediate of CGA 276854) is not required.
