Irritant / corrosive response data:
slight irritation of the conjunctiva, which was barely detectable after one week; slight but definite corneal injury as evidenced by staining with fluorescein
Other effects:
purulent exudate occurred two or more days after treatment

Any other information on results incl. tables

The irritation effects were not evaluated following common methods such as the Draize's method and scores cannot be quantified.

Applicant's summary and conclusion

Interpretation of results:
irritating
Remarks:
Migrated information
Executive summary:

Liquid chloroform was instilled into the eye of three rabbits, with and without washing of the eye after treatment. Chloroform was a slight irritant to the conjunctiva, which was reversible after one week. In addition, slight but irreversible corneal injury occurred as evidenced by staining with fluorescein. A purulent exudate occurred for two or more days after treatment. In conclusion, chloroform was found to be irritating to the rabbit's eye.
