Endpoint:
eye irritation: in vivo
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1969
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The study was performed with a +-45% active ingredient formulation, and not under GLP compliance. However, the study was conducted according to standards of that time, therefore the study is considered to be adequate, reliable and relevant.

At the readings made at 24, 48 and 72 hours, there was:

- discernible opacity or ulceration of the cornea other than a slight dulling of the normal luster.

- no inflammation of the iris other than slight deepening of the folds, or slight circumcorneal injection.

- a diffuse, deep-crimson red appearance of the conjunctivae with individual vessels, not easily discernible.

- an obvious swelling of the conjunctivae, excluding cornea and iris, with partial eversion of the lid.

- no destruction or irreversible change of any tissue in 24 hours or less.

Applicant's summary and conclusion

Interpretation of results:
irritating
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
This test item is sufficiently irritating to the rabbit eye so that precautions should be observed to avoid its introduction into or near the eyes.
Executive summary:

An in vivo eye irritation study was conducted with a first phase where 6 rabbits received 0.1 g test item containing 44 -46% active ingredient in one eye as an aqueous paste. Scoring at 24, 48 and 72 hours demonstrated non-reversible scores for cornea and conjunctivae in all animals and iris changes in one animal, all not reversible within 72 hours. Mean 24 -72h scores for cornea, conjuctiva and iris were 7.3/80, 7.3/20 and 1/10, respectively. There was no destruction or irreversible change of any tissue in 24 hours,but discernible opacity or ulceration of the cornea, diffuse, deep-crimson red appearance of the conjunctivae and obvious swelling of the conjunctivae with partial eversion of the lid were observed. In a second part of the study, 3 rabbits received 0.1 g as a 50% dilution of the above test item (22 -23% active ingredient). Scoring at 24, 48 and 72 hours demonstrated non-reversible scores in all 3 animals for cornea and conjunctivae, not reversible within 72 hours. Mean 24 -72h scores for cornea, conjuctiva and iris were 11/80, 10.7/20 and 0/10, respectively.

There was no destruction or irreversible change of any tissue in 24 hours, but discernible opacity or ulceration of the cornea, and diffuse, deep-crimson red appearance of the conjunctivae were observed.
