Test system

Vehicle:
unchanged (no vehicle)
Controls:
yes, concurrent no treatment
Amount / concentration applied:
100 mg
Duration of treatment / exposure:
24 hours
Observation period (in vivo):
72 hours

Details on study design:
The test item was applied to the left eye of each rabbit. The contra-lateral eye served as intra-individual control. Evaluation 1, 24, 48, and 72 hours after test item application by means of a magnifying lens. After 24 hours the eyes were rinsed with physiological saline solution.
At 24 and 72 hours, eyes were stained with Fluorescein-sodium-solution (0.01%) and investigated under UV-light by means of a slit lamp.
