If an eye gets lighted with a flashlight or other light sources the pupils will decrease their width. This pupillary response is a typical indicator in diagnostics. Is there any specific value which can be used as threshold to decide whether the test of pupillary response is passed or not?
EDIT: I read much about the pupillary response. There is much literature about how to do the checks and what are possible diagnoses but I was not able to find a specific value to decide whether the test of pupillary response is passed or not. I also asked medical staff and they told me you will see it and its about experience.
