Results and discussion
In vivo
Results
- Remarks on result:
- positive indication of irritation
- Remarks:
- Irritation index not determined because of corrosive effects
- Irritant / corrosive response data:
- Cornea: at 1 hour - no corneal opacity (degree 0, area 0); at 24 hours - corneal opacity (degree 4, area 4)
Iris: at 1 hour - no iridial irritation (0); at 24 hours - iris not discernible
Conjunctiva: at 1 hour - redness 2, chemosis 1, discharge 3; at 24 hours - redness 3 (diffuse beefy redness), chemosis 4 (swelling with lids more than half closed), discharge 3 (moistened considerable areas around the eye)
Eye filled with white mucus; eye, including nictitating membrane, discoloured (grey)
1 animal affected; due to the severity of the symptoms, no additional animals were tested.
Due to the severity of the symptoms at 24 hours, the tested animal was humanely killed. - Other effects:
- Eye processed for microscopic examination: revealed evidence of inflammation in the iris, uvea and sclera, anterior chamber, cornea, ocular muscles and eyelids; pronounced corrosive effects leading to ulcerations, coagulation necrosis and inflammatory changes.
No systemic toxic effects detected.
No changes were seen in the untreated eye.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye)
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In a guideline study, to GLP, potassium hexachloroplatinate produced corrosive effects following instillation into the eye of a single male rabbit.
- Executive summary:
In an OECD Test Guideline 405 study, conducted according to GLP, potassium hexachloroplatinate (99.5 mg) wasinstilled into the conjunctival sac of the left eye ofa single male White Russian rabbit.The other eye was untreated to serve as a control. Following instillation the eyelids were held closed by gentle finger pressure.The ocular response was assessed at 1 and 24 hr after instillation; corneal opacity, effects on the iris and conjunctival redness, chemosis and discharge were scored according to the Draize numerical scale. The treated eye as well as eye lids and nictitating membrane were assessed microscopically.
Corrosive effects were noted following instillation of the test material. The cornea was opaque and the iris was not discernible through the opacity. The conjunctiva showed diffuse beefy redness and swelling with lids more than half to completely closed. Discharge moistened considerable areas around the eye. The histological findings revealed a pronounced corrosive potential. The animal was humanely killed after 24 hr and no additional animals were tested due to the severity of the symptoms.No evidence of systemic toxicity was observed.
As the results were based on only one rabbit, it is not possible to give a definitive interpretation according to EU CLP criteria (EC 1272/2008). However, it is considered prudent to classify the test material for serious eye damage (Category 1), as the severe effects observed are not expected to be reversible.
