- Photoperiod (hrs dark / hrs light): 12 / 12
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: the untreated eye served as control
- Amount / concentration applied:
- TEST MATERIAL
- Amount applied: 0.1 mL of undiluted test article per animal into left eye
- Concentration: 100 % - Duration of treatment / exposure:
- The eye was not rinsed after application
- Observation period (in vivo):
- Scoring of irritation effects was performed approximately 1 h, 24 h, 48 h, 72 h and 7 d, 14 d, 21 d.
- Number of animals or in vitro replicates:
- 3 animals, 1 male and 2 female
- Details on study design:
- As a liquid, 0.1 ml (per animal) of CG 37-1586 was applied undiluted. The eyes of the animals were examined one day prior to test article administration. Animals with overt signs of ocular injury or irritation which may have interfered with the interpretation of the results were not used in the test. On the day of treatment, the test article was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of test article.
Scoring system
Grading of Ocular Lesions according toEEC 92/69/EEC COMMISSION DIRECTIVE, (1992)
CORNEA
Opacity: degree of density (area most dense taken for reading)
No ulceration or opacity 0
Scattered or diffuse areas of opacity (other than slight dulling of normal luster),
details of iris clearly visible 1
Easily discernible translucent area, details of iris slightly obscured 2
Nacreous area, no details of iris visible, size of pupil barely discernible 3
Opaque cornea, iris not discernible through the opacity 4
IRIS
Normal 0
Markedly deepened rugae, congestion, swelling, moderate circumcorneal hyperemia, or injection, any of these or combination of any thereof, iris still reacting to light (sluggish reaction is positive) 1
No reaction to light, hemorrhage, gross destruction (any or all of these) 2
CONJUNCTIVAE
Redness (refers to most severe reading of palpebral and bulbar conjunctivae when compared with control eye)
Blood vessels normal 0
Some blood vessels definitely hyperemic (injected) 1
Diffuse, crimson color, individual vessels not easily discernible 2
Diffuse beefy red 3
Chemosis: lids and/or nictitating membranes
No swelling 0
Any swelling above normal (including nictitating membranes) 1
Obvious swelling with partial eversion of lids 2
Swelling with lids about half-closed 3
Swelling with lids more than half-closed 4
