Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: right eye is control
Amount / concentration applied:
0.1 ml
Duration of treatment / exposure:
exposure 24 hours
Observation period (in vivo):
The clinical eye examination was carried out in the periods
in 1, 24, 48 and 72 hours after application of the sample.
In 1 hour after application the eye reactions were
considered without the flush of the eye with water. In 24
hours the assessment was carried out after wary flush of the
eye with water. The examination of the cornea mesh defect
was carried out after decolouration with fluorescein. The
reaction after 72 hours after application was assessed by
using of fluorescein.
Number of animals or in vitro replicates:
3

Other effects:
The clinical eye examination was carried out in the periods in 1, 24, 48 and 72 hours after application of the sample. In 1 hour after application the eye reactions were considered without the flush of the eye with water. In 24 hours the assessment was carried out after wary flush of the eye with water. The examination of the cornea mesh defect was carried out after decolouration with fluorescein. The reaction after 72 hours after application was assessed by using of fluorescein. Results: In 1 hour after exposure a slight redness was observed at the first and third animals and slight ophthalmorrhoea was was observed at first animal. No observable changes was noted during the observation period - in 24, 48 and 72 hours after application of the sample among all animals.
