Irritant / corrosive response data:

Response was assessed in a single animal. Well defined conjunctival chemosis and moderate redness were observed 1, 24 and 48 hours post-exposure. Seventy-two hours after exposure, slight chemosis and severe redness were observed. Slight redness was still observed after 7 and 14 days. Slight discharge and chemosis were noted after 14 days after dosing. Slight corneal opacity with the area of cornea involved greater than half was observed from 1 hour post-exposure up to the end of the observation period (21 days after treatment). The extension of the opacity gradually decreased from 48 hour post-exposure.

AVERAGE SCORE
- Cornea: 1.0
- Iris: 0.0
- Conjuntivae (Redness): 2.3
