SCORING SYSTEM:
- The grades of ocular reaction were scored according to Draize.
- An animal exhibited a positive reaction if the test article produced at any observation one or more of the following signs: opacity of the cronea (other than a slight dulling of the normal luster), inflammation of the iris (other than a slight deepening of the rugae or a light hyperemia of the circumcorneal blood vessels) or an obvious swelling in the conjunctivae (excluding the cornea and iris) with partial eversion of the eyelids or a diffuse crimson color with individual vessels not easily discernible.

- Irritant / corrosive response data:
- No corneal, iris or conjunctivae irritation was observed in the untreated eyes of the rabbits at any time point. No corneal or iris irritation was observed in the treated eyes of the rabbits at any time point. Conjunctival redness and chemosis (scores of '1') were observed at 1 and 24 hours post dose with only one score of '1' observed at 48 hours for redness. Scores of '2' for discharge were observed at 1 hour. All three animals were observed to be normal at 72 hours and the study was terminated.
- Other effects:
- Mortality/clinical observations:
- No mortality or adverse clinical signs were observed in the animals during the study.
Applicant's summary and conclusion
- Interpretation of results:
