- Washing: the substance was not washed out.
SCORING SYSTEM: according to a modified Draize scale.
Chemosis and cornea (opacity-degree of density):
0 = none
1 = slight
2 = well-defined
3 = severe
4 = very severe
Conjunctivae redness:
0 = normal
1 = slight
2 = well-defined
3 = severe
Iris:
0 = normal
1 = circum-corneal injection
2 = iritis
Area of cornea involved:
1 = > 0; < 1/4
2 = >= 1/4; < 1/2
3 = >= 1/2; < 3/4
4 = >= 3/4
Discharge:
0 = normal
1 = slightly increased
2 = clearly increased
3 = distinctly increased
OBSERVATIONS:
Weight determination: shortly before application of the test substance.
Symptoms were recorded.
No further information on the study design was stated.
