Irritant / corrosive response data:
No corneal effects were detected. The iris appeared inflammed in one animal at 1 h post-treatment, but it was fully reversible within 24 h. Minimal irritation of the conjuctivae was seen in two animals at 24 h.

Conclusions:
The substance is not an eye irritant.
Executive summary:

In this eye irritation study, 0.5 ml of SER-AD FX 511 was instilled into the conjunctival sac of the right eye of 3 young adult New Zealand White rabbits (1 female and 2 males). Animals were then observed for the following 72 h. Irritation was scored using the Draize scheme for unwashed eyes at time point of 24, 48 and 72 h post-treatment. No corneal effects were detected. The iris appeared inflammed in one animal at 1 h post-treatment, but it was fully reversible within 24 h. Minimal irritation of the conjuctivae was seen in two animals at 24 h. SER-AD FX 511 induced slight irritation that was reversed during the study period. On the basis of this study, SER-AD FX 511 does not warrant classification as being an eye irritant.
