Any other information on results incl. tables

Severe ocular reactions with obvious signs of pain were seen in the single treated animal approximately 4 hours after treatment. Conjunctival reactions , identiffied by beefy redness, with haemorrhage of the capillaries of the conjunctival and nictitating membranes, severe chemosis and an extensive discharge were noted. The severity of the chemosis precluded examination of the cornea and iris at this stage.

For Humane reasons, the animal was killed and the cornea and iris were examined immediately after death. Diffuse corneal opacity and iridial inflammation were noted at this time.
