Test animals / tissue source

Species:

rabbit

Strain:

New Zealand White

Details on test animals or tissues and environmental conditions:

TEST ANIMALS
- Source: Simonson laboratory in Gilroy, California
- Weight at study initiation: 2-2.5 kg
- Diet (e.g. ad libitum): standards rabbit pellets

Test system

Vehicle:

unchanged (no vehicle)

Controls:

other: untreated eye of the same animal

Amount / concentration applied:

Amount applied: 0.1 ml

Duration of treatment / exposure:

eyes were kept unwashed

Observation period (in vivo):

48 h

Number of animals or in vitro replicates:

3

Details on study design:

- Normal rabbit eyes were preselected on the basis of absence of grossly visible staining by a 5% aqueous solution of fluorescein sodium, flushed with distilled water 20 seconds after instillation. After a two hours interval, to allow the eyes to return to normal, a compound was instilled into one eye. The compound was dropped on the center of the cornea while the lids were retracted, about one minute later the lids were released.

REMOVAL OF TEST SUBSTANCE
- Washing (if done): no

SCORING SYSTEM: according to Draize (1955). Individual scores for each irritation parameters were not observed, a total score was determined. Grading of scores was as follows:
0-30 = mild
31-60 = moderate
60 = severe
