SCORING SYSTEM:
The evaluation of eye irritation is performed according to the quoted guidelines. In addition to specific observations recommended by the regulatory authorities, evaluations were made of discharge from the eye and the area of cornea affected by the lesions.
Area of cornea involved (ar):
1 = >0 <= 1/4
2 = > 1/4 < 1/2
3 = > 1/2 < 3/4
4 = > 3/4
Discharge (di):
0 = No discharge
1 = Any amount different from normal (does not include small amounts observed in inner canthus of normal animals)
2 = Discharge with moistening of the lids and hairs just adjacent to lids
3 = Discharge with moistening of the lids and hairs, and considerable area around the eye
Description of any ocular findings not covered by this scale were recorded.
EVALUATION OF RESULTS
For evaluation, the calculation of the mean values of corneal opacity, iris, conjunctival redness and chemosis for readings 24, 48 and 72 hours were quoted. Additionally, the reversibility of the observed findings was taken into account.
The evaluation is based on the criteria of Annex VI of the Commission Directive 67/548/EEC that were in place on the date of report signature.
TOOL USED TO ASSESS SCORE: hand-slit lamp (Daylight tubes "Lumilux" (L 58W/860 PLUS ECO 25X1, Osram, Germany)
