TOOL USED TO ASSESS SCORE: a handheld torch
Results and discussion
In vivo
- Irritant / corrosive response data:
- Mild inflammation or a diffuse crimson-red colouration of the conjunctivae was seen in three rabbits. The eyes of two of these rabbits were normal by Day 2 and that of the third by Day 4. No ocular reactions were recorded in the remaining three rabbits.
