- Diet: approx. 120 g/day x animal standard diet, ssniff K, special diet for rabbits supplied by ssniff Spezialfutter GmbH, D- 4770 Soest, germany
- Water (ad libitum): drinking water quality from the Stadtwerke Bielefeld
- Acclimation period: 1 day under test conditions before application of the test substance. Veterinary supervision of the animal ws done before start of the study.
Preliminary inspection of the eyes: before application of the test substance.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 21.5 - 22.5
- Humidity (%): 40 - 70
- Photoperiod: 12 hours dark/light cycle
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.18 g (representing a volume of about 0.1 mL) of the test substance were applied into the conjunctival sac of the right eye. Then both lids were briefly closed by gentle finger pressure. The other eye of the animal was not treated and acted as control. - Duration of treatment / exposure:
- not applicable
- Observation period (in vivo):
- 1 hour after application
- Number of animals or in vitro replicates:
- 1 male rabbit
- Details on study design:
- REMOVAL OF TEST SUBSTANCE
- Washing (if done): The treated eye was not rinsed.
SCORING SYSTEM: Signs of irritation on the cornea, iris, and conjunctiva were assessed quantitatively and qualitatively using the Draize scale. In addition, attention was paid to the occurrence of further reactions on the eye (e.g. corrosive effects) and to clinical symptoms (systemic toxic effects).
TOOL USED TO ASSESS SCORE: The treated eye was examined using a Cliptrix pencil light (supplied by Varta, Hannover, No. 645).
SACRIFICE
2 hours after removal of the patch the animal was sacrificed with T 61(R) (supplied by Hoechst Veterinär GmbH, D-8044 Unterschleißheim).
PATHOLOGY
The treated eye as well as eye lids and nictitating membrane were removed, fixed (in SUSA fixative according to HEIDENHAIN for approximately 24 hours, thereafter in 4 % formaldehyde solution according to LILLIE), trimmed, embedded in paraffin wax, sectioned at approximately 4 µm, and stained with hematoxylin and eosin (H&E). The slides were examined microscopically.

- Time point:
- other: 1 hour after exposure
- Score:

- Max. score:
- 4
- Reversibility:
- not specified
- Irritant / corrosive response data:
- The single application of 0.18 g (representing a volume of about 0.1 mL) silver(I)-sulphate into one conjunctival sac of one rabbit caused severe changes.
1 hour after application the cornea was opaque and the iris was not discernible through the opacity (grade 4). The whole corneal area was involved. In addition, the whole corneal area was grey-green discoloured.
An evaluation of the iris was impossible because of the opaque cornea.
The conjunctiva was white-green discoloured one hour after application. In addition, obvious swelling with partial eversion of the lid (grade 2) occurred.
Discharge moistened lids and hair just adjacent to lids (grade 2).
At microscopical examination of the treated eye the conjunctiva and the nictitating membrane showed acute coagulation necrosis of the epithelium and beginning granulocytic cell infiltration. The surface was covered with brown-black material (test material). In addition, focal loss of the corneal epithelium as well as acute coagulation necrosis of the corneal epithelium which was brown-black discoloured by the test material were found. The anterior eye chamber was filled with granular eosinophilic material.
The untreated eye did not show any changes. - Other effects:
- There were no systemic toxic effects after conjunctival application of the test substance.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Silver (I) sulphate is corrosive to the eyes.
According to the EC-Commission directive 67/548/EEC and its subsequent amendments, the test substance is classified as risk of serious damage to eyes.
According to the EC-Regulation 1272/2008 and subsequent regulations, the test item is classified as Category 1.
