Any other information on results incl. tables
Cornea and iris were free of any signs of irritation during the whole observation period.
Slight conjunctival redness (grade 1) was noted in all animals from 1 hour up to hour 72 hours after application and persisted in one animal until study day 7.
Moderate conjunctival chemosis (grade 2) was noted in one animal 1 hour after application. This finding decreased to slight conjunctival chemosis (grade 1) and was noted from hour 24 until study day 7 in this animal. In another animal slight conjunctival chemosis (grade 1) was observed at hour 1 only, while in the third animal this finding was seen from hour 24 until study day 7.
In all animals severe discharge (grade 3) was noticed at hour 1. In one of these animals slight discharge (grade 1) was observed at hour 48.
Additional findings like injected scleral vessels in a circumscribed or circular area were noted in the animals from hour 1 until hour 48 at the latest. Hair loss was seen in two animals from day 7 until day 14 or on day 14, only. Scaling on the eye lids or under the eye was observed in one animal on study day 7, while in another animal this finding was noticed from study day 7 until study day 14. Incrustations on the eye lids or under the eye were observed in one animal on study day 7 and in the two other animals from study day 7 until study day 14. In one of these animals the incrustation, localized under the eye, was pea-sized on study day 7.
The ocular reactions were reversible in one animal within 7 and in two animals within 14 days after application.
Mean scores calculated for each animal over 24, 48 and 72 hours were 0.0, 0.0 and 0.0 for corneal opacity, 0.0, 0.0 and 0.0 for iris lesions, 1.0, 1.0 and 1.0 for redness of the conjunctiva and 1.0, 0.0 and 1.0 for chemosis.
