Results and discussion

In vivo

Irritant / corrosive response data:
In the observations made after application, iris congestion (score points: 1); and in respect of the conjunctiva, flushing (score points: 1), edema (score points: 1) and ocular discharge / secretion (score points: 1) were seen. These local reactions had all disappeared by 48 hours after applying the test substance. No local reactions were observed in the cornea throughout the observation period (Table 2).
Maximum value up to 72 hours after application: 11 (1 hour after application).
