Eye irritation
Administrative data
- Endpoint:
- eye irritation: in vivo
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 1989/10/09 - 1989/10/26
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: A read-across study with an analogous substance was scientifically justified, because it was conducted from the disodium salt to the monosodium salt of the test substance.

- SCORING SYSTEM:
The data relating to the conjunctivae were designated by the letters A (redness), B (chemosis) and C (discharge), those relating to the iris designated by the letter D and those relating to the cornea by the letters E (degree of opacity) and F (area of opacity). For each tissue the total score was calculated as follows:
Total score for conjunctivae = (A + B + C) x 2
Total score for iris = D x 5
Total score for cornea = (E x F) x 5
TOOL USED TO ASSESS SCORE: standard ophthalmoscope

Applicant's summary and conclusion
- Interpretation of results:
- Category II
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Executive summary:
The test substance was investigated for its eye irritation potential in accordance with OECD guideline 405 under GLP conditions. The mean scores for cornea, conjunctiva, iris effects and chemosis were 1.8, 2.9, 1 and 2.4. All effects were reversible after 14 days. Consequently the test substance is considered to be eye irritating.
