Irritation: No abnormal findings were observed in the treated eye of any animal after 48 hours treatment. However, after 1 hour instillation slight reddening of the conjunctivae, sclerae and slight swelling (chemosis) of the conjunctivae was observed in 3 animals. Reddening of the conjunctivae persisted in 1 animal at 24 hour Coloration: White remnants of the test item were observed in the eye at the 1-hour reading. Corrosion: No corrosion of the cornea was observed at any of the reading times.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of this study, Nomcort HK-G is not irritating to the eye
- Executive summary:
The primary eye irriation potential of Nomcort HKG was investigated according to OECD test guideline no. 405. The test item was applied by instillation of 0.1 g into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test item instillation. The mean score was caldulated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, sparately. The individual mean scores for corneal opacity and iris were 0.0 for all three animals. The individual mean scores for the conjunctivaed were 0.33, 0.00 and 0.00 for reddening, respectively and 0.00 for chemosis in all animals.
The instillation of Nomcort HKG into the eye resulted in mild, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae, discharge and chemosis. These effects were reversible and were no longer evident 48 hours after treatment. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. White test item remnants was present in two animals at the 1 hour reading.
No clinical signs were observed.
Thus, the test item did not induce significant or irreversible damage to the rabbit eye.
