Test material
Constituent 1
Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS
- Source: Charles River, Deutschland GmbH, Stolzenseeweg 32-36, 88353 Kisslegg, Germany
- Weight at study initiation: 2.3 - 2.4 kg
- Diet: rabbit diet "Altromin 2123" (supplier: Altromin, D-32791 Lage, Lippe, Germany), ad libitum.
- Water: The animals had free access to bottles with domestic quality drinking water acidified with hydrochloric acid to pH 2.5 in order to prevent microbial growth.
- Acclimation period: no data
ENVIRONMENTAL CONDITIONS
- Temperature:20 °C ± 3°C
- Humidity:55 % ± 15 %
- Air changes: 10 times/hour
- Photoperiod: cycle of 12 hours light and 12 hours darkness. Light was on from 06 to 18 h
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: Only the left eye was treated. The right eye remained untreated and served as control.
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied: 0.1 mL of test item - Duration of treatment / exposure:
- 0.1 mL ofthe test article was placed in the left eye ofthe rabbits by gently pulling the lower Iid away from the eyeball to form a cup into which the test article was dropped. The Iids were then gently heldtagether for 1 second.
- Observation period (in vivo):
- The eyes were examined and the grade of ocular reaction was recorded one hour and 24 hours later. The eyes were also examined 48 and 72 hours after the treatment.
- Number of animals or in vitro replicates:
- three females
- Details on study design:
- The day before testing both eyes of the animals were examined with a hand held inspection lamp fitted with white and UV -light and magnifying glass with 2 x magnification to ensure there were no defects or irritation. The examination was performed before and after instillation of Fluorescein.
After the first 24 hour reading Fluorescein was instilled. After rinsing with 20 mL 0.9 % sodium chloride solution the eyes were examined again using UV -light to detect possible corneal damage.
