SCORING SYSTEM:
Opacity:
0 = no ulceration / opacity
1 = slight dulling, details of iris clearly visible
2 = easily discernible translucent area, details of iris slightly obscured
3 = nacrous area, details of iris not visible, size of pupil barely discernible
4 = opaque cornea, iris not visible through opacity
Iris:
0 = normal
1 = markedly deepened rugae, conjestion, swelling, moderate circumcorneal hyperaemia, injection (any of or combination of) iris still reactive to light
2 = no reaction to light, haemorrhage, gross destruction (or any of the above)
Conjunctivae:
0 = blood vessels normal
1 = some vessels definitely hyperaemic
2 = diffuse, crimson colour, individual vessels not easily discernible
3 = diffusy beefy red
TOOL USED TO ASSESS SCORE: hand-slit lamp

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the experimental conditions CGA 224433 tech. induced irritation of the cornea, iris and conjunctiva when instilled into the corneal sac of albino rabbits.
In only one animal, reactions reached significance and the redness of conjunctival irritation was not fully reversible until the final test day at 21 days. - Executive summary:
Testing was performed to determine the acute eye irritation/corrosion potential of CGA 224433 tech. on albino rabbit eye.
Although the results show that readings reached the threshold of significance and irritation was not fully reversible until the final test day, as this was observed in only one out of three tested animals, then according to EC Directive No 83/467/1983, CGA 224433 tech. can be classified as non-irritant to albino rabbit eye.
Therefore no hazard symbol or warning should be assigned.
