Controls:
other: eye, which remains untreated, serves as a control
Amount / concentration applied:
TEST MATERIAL
- Amount: 0.1 mL
- Concentration (if solution): undiluted
Duration of treatment / exposure:
no washing
Observation period (in vivo):
Scoring 1, 24, 48, and 72 h after instillation

1 male and 2 females
Details on study design:
No signs of ocular injury or irritationin any test animal.
On the day of treatment, 0.1 mL of Biofert Plusz (containing 0.028 g of the dry mass) was placed in the conjunctival sac of the left eye of each animal.
SCORING SYSTEM: according to Guideline

Irritant / corrosive response data:
No abnormal findings in the cornea or iris of any animal at any of the scoring intervals; slight reddening of the conjunctivae (score 1) noted in all three animals 1 h after treatment and persisted in two animals for up to 48 h; slight swelling (chemosis) of the conjunctivae in one female only 1 hour after instillation. Slight reddening of the sclerae was present in all animals 1 hour after treatment. All effects reversible 72 h after instillation. No staining produced by the test item.
Other effects:
No clinical signs of systemic toxicity were observed in the animals during the study.
The body weights of all rabbits were considered to be within the normal range of variability.
