SCORING SYSTEM:
Cornea
Opacity: degree of density
No ulceration or opacity 0
Scattered or diffuse areas of opacity (other than slight dulling of normal lustre), details of iris clearly visible 1
Easily discernible translucent area, details of iris slightly obscured 2
Nacreous area, no details of iris visible, size of pupil barely discernible 3
Completely opaque cornea, iris not discernible through the opacity 4
Iris
Normal 0
Markedly deepened rugae, congestion, swelling, moderate circumcorneal hyperaemia or injection, iris still reacting to light (sluggish reaction is positive) 1
No reaction to light, haemorrhage, gross destruction 2
Conjunctivae

TOOL USED TO ASSESS SCORE: hand-slit lamp. To define epithelial damage, one drop of a 1% fluorescein solution was applied to the corneal surface 24 hours after administration of the test substance. Evaluation was performed by means of ultraviolet illumination in a darkened room and diffuse white illumination.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The results of the exposure of the test substance to the eye indicate that the test substance may be regarded as not irritating to the eye.
- Executive summary:
The acute ocular irritation/corrosion study was performed according to the OECD Guideline No. 405 and EU Method B.5. The test item in the amount of 0.1 mL was placed into the conjunctival sac of one eye of each of three rabbits. 24 hours after instillation of the test substance the treated eye was rinsed with normal saline. Eye irritation was scored and recorded at 1, 24, 48 and 72 hours and 7 days after the end of the exposure. The results of the exposure of the test substance to the eye indicate that the test substance may be regarded as not irritating to the eye.
