The pupil, a small circular hole in the center of the iris of an animal or human eye, is the passage of light into the eye, and can be constricted by the contraction of the sphincter pupillae on the iris. When patients have cerebral hernia, elevated intracranial pressure, dying and severe brain injury, the pupils are usually enlarged, so the condition of the patients can be judged according to the size of the pupils of the patients.
Currently, the main methods for determining the pupil size include: the subjective judgment method is characterized in that the pupil is directly irradiated by a common pupil light pen, and medical personnel judge the size of the pupil, so that the subjective performance is strong, and the error is large; visual electrophysiological examination, including Electrooculogram (EOG), Electroretinogram (ERG), and Visual Evoked Potential (VEP), can avoid subjective factors of medical staff, but detection is extremely direct contact with human eyes, is prone to infection, and is prone to cause excessive pupil contraction due to human self-defense, and detection data is inaccurate.
