Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Since the treated animals exhibited redness of conjunctivae ≤ 1.67, corneal opacity ≤ 1.67, chemosis ≤ 3.00, lesions in iris ≤ 1.33 and the lesions in the eye were not reversed at day 21 observation in 3 out of 3 treated animals, hence the outcome of result qualify for category 1 of the classification criteria, hence CHUA is classified as per Harmonised Integrated Classification System as "irreversible effects" to rabbit eyes.
- Executive summary:
The acute eye irritation/corrosion study of CHUBA in Rabbits was investigated according to OECD test guideline 405. The test item, 0.1g was placed in the conjunctiva! sac of the left eye of a single male rabbit. Eye reactions were observed up to 72 hours approximately post treatment, the test was completed using the remaining two male rabbits to confirm the findings of the initial test. The scoring of eye reactions was performed at 1, 24, 48, 72 hour, day 7, 14 and 21 for all the treated animals post test item instillation. The mean score was calculated across 3 scoring intervals (24, 48 and 72 hour post treatment) for each animal for corneal opacity, iris, conjunctival redness and chemosis. The individual mean score of opacity, iris, conjunctivae and chemosis for Animal No. 01 was 1.00, 1.00, 1.67 and 3.00, for Animal No. 02 and 03 were 1.67, 1.33, 1.33 and 3.00.
In Animal No. 01, instillation of test item in rabbit left eye caused redness of conjunctivae with some blood vessels definitely hyperaemic at 1 hour observation post test item instillation. Redness of conjunctivae with diffuse, crimson color; individual vessels not easily discernible was observed at 24 and 48 hour observation. Animal continued to exhibit conjunctival redness, the severity was slightly reduced to conjunctivae with some blood vessels definitely hyperaemic at 72 hour and the lesion fully reversed and appeared normal on day 7. Some swelling above normal (includes nictitating membranes) of chemosis was observed at 1 hour observation post test item instillation. Chemosis with obvious swelling with partial eversion of lids was observed at 24 hour observation. Swelling, with lids about half closed was observed at 48 hour and swelling, with lids about more than half closed was observed at 72 hour observation. The severity of Chemosis was slightly reduced to some swelling above normal (includes nictitating membranes) on day 7 and appeared normal on day 14 of observation. No opacity was observed at 1 hour and 24 hour observation whereas diffuse areas of opacity involving one quarter but not zero and details of iris clearly visible was observed at 48 hour and easily discernible translucent area of opacity with greater than one quarter, but less than half was observed at 72 hour observation. The severity increased to opaque cornea and iris not discernible through the opacity greater than three quarters, upto whole area on was observed on day 7, 14 and 21 observation. No lesion in iris was observed at 1, 24, hour and iris reactive to light (a sluggish reaction is considered to be an effect) was observed at 48 hour observation. At 72 hour the severity increased to no reaction to light and continued to exhibit on days 7, 14 and 21 observation.
In Animal No. 02 and 03, instillation of test item in rabbit left eye caused redness of conjunctivae with some blood vessels definitely hyperaemic at 1 hour observation post test item instillation. Redness of conjunctivae with diffuse, crimson color; individual vessels not easily discernible was observed at 24 and the severity was slightly reduced to conjunctivae with some blood vessels definitely hyperaemic at 48 and 72 hour observation. This lesion fully reversed and appeared normal on day 7. Some swelling above normal (includes nictitating membranes) of chemosis was observed at 1 hour observation post test item instillation. Chemosis with obvious swelling with partial eversion of lids was observed at 24 hour observation. Swelling, with lids about half closed was observed at 48 hour and swelling, with lids about more than half closed was observed at 72 hour observation. The severity of Chemosis was reduced to some swelling above normal (includes nictitating membranes) on day 7 and appeared normal on day 14 of observation. No opacity was observed at 1 hour observation whereas diffuse areas of opacity involving one quarter but not zero and details of iris clearly visible was observed at 24 hour and easily discernible translucent area of opacity with greater than one quarter, but less than half was observed at 48 and 72 hour observation. The severity of lesion increased to opaque cornea and iris not discernible through the opacity greater than three quarters, upto whole area was observed on day 7, 14 and 21 observation. No lesion in iris was observed at 1, 24, hour and no reaction to light was observed at 48 and 72 hour observation. This lesion was continued to exhibit on days 7, 14 and 21 observation. After 21 days of observation all the treated animals (Animal No. 01, 02 and 03) were sent for terminal sacrifice.
Based on the above findings, in 3 out of 3 animals, the eye lesions persisted till day 21 observation. The experiment was terminated on day 21 considering the test item had "irreversible effects" on the eye. No clinical signs were observed in any of the test animals throughout the acclimatization period and during experimental period. The body weights of all the animals were considered to be within the normal range of variability commonly observed for this species, strain and age. No abnormalities were detected internally in any of the treated animal during necropsy at terminal sacrifice. Moderate corneal opacity and slightly conjunctivae edematous was present in left eye of Animal No. 01. Marked corneal opacity, conjunctiva edema slightly present in left eye of Animal No. 02 and 03 were observed externally during necropsy at terminal sacrifice.
