Test system
- Vehicle:
- not specified
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- ca 0.1 ml of the test substance (0.035 g)
- Duration of treatment / exposure:
- Single treatment
- Observation period (in vivo):
- 14 days
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- The in vitro/ex vivo Non-GLP Chicken Enucleated Eye Test did not show severe signs of irritation. Therefore, it was decided to proceed with the in vivo test. Both eyes of the rabbits selected were examined just before testing. Only rabbits without observable eye defects were used. The study was carried out with three rabbits and each rabbit was treated as follows: An amount of ca 0.1 ml of the test substance (0.035 g) was instilled in the conjunctival cul-de-sac of one of the eyes. After administration, the upper and lower eye lid were carefully closed and subsequently held together for at least one second before releasing, to prevent loss of material. The other eye remaining untreated, served as a control. The reactions of the test eyes were judged at circa one, 24, 48, 72 hand at 7 and 14 days after treatment using the scoring scale.

- Irritant / corrosive response data:
- At 1 h after treatment, moderate redness and moderate swelling of the conjunctivae and moderate ocular discharge were observed in the three rabbits.
At 24, 48 and 72 h after treatment, slight opacity and slight iritis were observed in one rabbit, while moderate or severe redness and slight or moderate swelling of the conjunctivae and slight, moderate or severe ocular discharge were observed in the three rabbits.
At 7 days after treatment slight redness and moderate swelling of the conjunctivae were still observed in the third rabbit (no. 36). - Other effects:
- At one hour after treatment, amounts of the test substance were still present in the conjunctival cul-de-sac of the rabbits. These remnants were removed by rinsing of the eye with physiological saline.
In addition, a haemorrhage of the conjunctivae and ischemic necrosis (only animal no. 36) were observed in the rabbits at 48 and 72 h after treatment.
At 7 days after treatment, eye effects had cleared in two rabbits.
At 14 days after treatment, eye effects had cleared in the third rabbit as well.
