Although, i had to sign a consent form before the operation indicating some risk. However, anesthetics have greatly improved over recent years and are considered safe.

The mechanism by which noxious stimuli dilate pupils during anesthesia in humans remains unknown.

Unilateral pupillary dilatation after general anesthesia has sinister implications, which might prompt further investigations.

My cat was anesthetized yesterday morning for a dental, and his pupils are still completely dilated this morning.can it take more than 24hrs to wear off?
