As people know that “eyes are the window to the soul”, researchers have found that the connection can get deeper into the brain as well.
Pupils respond to more things than light. They indicate arousal, and fear, as well as changes in emotions, mental exhaustion, and astonishment or interest. Pupil dilation is one of the crucial tools for checking the neurological balance of the body and mind as well.
How experts use the pupil dilation factor
If a patient has a dilated pupil that does not naturally respond to light or any external emotions, it should be considered that the person is going through serious neurological damage.
Many sorts of damage can affect the cranial nerves. The visual capacity of humans is dependent on light indeed, but other sensory factors may affect the sensation. Dilation of pupils may lead to concerns related to brain damage, brain hemorrhage, heart attack, lesser oxygen supply to the brain, comatose condition, as well as other neurological damage due to some external influence like drugs.
How can doctors measure pupils?
The earlier ways of pupil size assessment have changed. It is no longer a manual process. Nowadays, doctors measure pupil size with advanced device like NPi pupillometer. This machine can accurately provide the metrics regarding the right size of the pupils. The slightest changes in the sizes, alongside other factors, can help doctors understand what kind of neurological problems or damages they are dealing with.
The pupillometer can take over 90 photographs of pupils within 3 seconds. It can also provide a distinct idea regarding the status of neurological conditions through pupil size measurement. Doctors can also detect the history of seizures through pupillometry.
Pupil and mental health
The first detection of a connection between pupil measurement and mental health came between 1960 to 1970. Measurement by an American institute with 500 individuals of different ages in recent years has stabilized the concept of connection between pupils and emotional intelligence.
Rather than tough and time-consuming tests, modern machines like NPi-300 pupillometer can accurately provide all the details that the medical professionals require through measuring thepercent change in pupil size.
Pupil sizes are negatively correlated with age. Older people tend to have constricted pupils, while younger ones have comparatively dilated ones. It helps maintain healthy brain activity so that the distant brain regions can perfectly work together to accomplish challenging tasks and goals.
Are dilated pupils always bad?
Here you need to understand what “bad” means. If a person is in a comatose state, he or she may have dilated pupils. That would be bad indeed because it signifies a non-responsive state. The Pupillary Response in Traumatic Brain Injury may also indicate that the person is having trouble coping with his life.
On the other hand, dilated pupils may be caused due to ophthalmic issues as well. Anisocoria can dilate pupils, and that would be treatable. Also, when you go under eye exams, your pupils will be dilated by medicines.
How to measure pupil size
Pupil sizes can be checked by looking at them. But when a medical measurement is required, pupil dilation can be checked with advanced machines. The best and easiest of them all is an NPi-pupillometer.
Which injuries can dilate people and affect emotional intelligence?
Emotional injuries can be a cause of many issues. But when it affects the body even from the outside, pupil size assessment may help figure them out. As an example, a patient suffering from Parkinson’s disease or Alzheimer’s may tend to lose emotional stability at times. Measuring the size of the pupils can help doctors figure out the reasons behind a drastic behavior or reasons for cognitive inability.
Brain injuries, especially traumatic brain injuries can vividly affect brain functions. The cranial nerves can be affected, and serious pupil dilation can be measured as a result of such events. Brain swelling, acute stroke, as well as intracranial tumor, increased intracranial pressure, and even migraine headaches can lead to the abnormal dilation of pupil size.
When you consider emotional intelligence with the change of pupillary response, you can attribute the changes to the physical deteriorations, which broadly affect the usual visual capacities and pupillary measures.
