Thank you for your query.
As the injury
occurred 2 nights back and your daughter is as active as before then there is nothing to worry about. In case she had been vomiting
or was disoriented then it was a reason for being concerned. Do not worry about the dilated pupils as they are reacting normally to light.
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
