Pupilometry is a method of examining the eye to determine brain and nervous system disorders.
This method helps to detect neurological disorders. The introduction of digital pupilometers has made it easier for doctors to measure pupil size and diagnose these neurological conditions. Doctors use this device to measure the diameter of a patient’s pupil.
This post will discuss how the pupilometer device works and how it changes the healthcare industry.
What is a pupilometer?
A pupilometer is a device that measures the size of your pupils. The pupilometer is fast and easy to use, unlike other methods such as CT or MRI scans, which are expensive, invasive, and time-consuming.
What does the pupilometer check?
1. Pupillary distance
Pupillary distance or PD is the distance between your pupils.
It’s measured in millimeters and is used to determine how much light enters your eyes. Pupilometer measures PD using a high-quality camera to capture an image of both eyes simultaneously.
2. Pupil reactivity
Many factors can affect pupil reactivity, such as light, stress, drugs, and disease. When measuring pupil size, it is essential to consider what you use to measure it because some tools are not accurate enough for medical use.
The pupilometer, however, uses the high-quality camera, which allows for accurate measurements down to 1/100th millimeter with no ambiguity or margin of error that other measurement methods may have been subject to before its invention.
The link between the pupils and traumatic brain injury
The pupils are often an excellent indicator of brain injury.
When they don’t react to light, it can show that something is wrong. Most times, the pupils become smaller than normal after a traumatic event, such as an accident or fall. Blood vessels constrict in response to pain or other stimuli (like bright lights).
The reason this happens has to do with the way our brains work.
When we have an injury anywhere in our body, more blood flows toward the injury site for healing purposes. Another thing that could happen is that one pupil might dilate more than the other—this can also be a sign of brain damage even if it doesn’t happen immediately after impact or trauma.
What are the other ways of diagnosing traumatic brain injuries?
There are other ways of diagnosing traumatic brain injuries, and these include:
1. Computerized tomography (CT) scan
A computerized tomography (CT) scan is a medical imaging technique that uses X-ray technology to create cross-sectional images of the inside of an object.
A CT scan can diagnose various diseases, including cancerous tumors and brain injuries due to trauma, which will help doctors determine how best to treat them. Unfortunately, CT scans are not as accurate at diagnosing brain injuries as magnetic resonance imaging (MRI).
2. Magnetic resonance imaging or MRI
MRI or Magnetic resonance imaging is nothing but a non-invasive imaging technique used to detect brain injuries and tumors.
MRI devices use a powerful magnetic field and radio waves to create cross-sectional images of the patient’s brain. The images let doctors see the soft tissues inside the patient’s skull, including the blood vessels that supply oxygenated blood to different brain regions. Health professionals have used MRI for decades as an effective way for them to take pictures of the brain so they can assess how much damage there has been and where exactly it’s located to determine whether surgery would be an appropriate treatment.
3. Electroencephalography (EEG)
EEG is a test that measures the electrical activity of the brain.
It does not require the patient to lie down, but may be uncomfortable for some individuals. EEGs are usually used to diagnose traumatic brain injuries. These machines measure brain waves (electrical impulses) through electrodes on the scalp or by placing them under the patient’s scalp at various points around the head.
The advantages of using a pupilometer over other diagnostic options for traumatic brain injuries
Doctors can use a pupilometer to accurately diagnose traumatic brain injuries in patients.
The advantage of using a pupilometer over other diagnostic options is that it is faster and more reliable than other methods, such as CT and MRI scans. A CT scan can take up to 40 minutes per test, while an MRI scan can take up to an hour per test. The average time it takes for a doctor to diagnose a traumatic brain injury with the pupilometer is just under two minutes.
Other advantages include
1. Improved Quality of Neurological Exam
The pupilometer has made a major impact on the way physicians perform neurological exams.
The tool was develop to measure pupil size and reactivity, which helps diagnose traumatic brain injuries and other neurological disorders. Previously, doctors relied on their eyesight and a flashlight to evaluate whether an injury had occurred.
However, this can be unreliable as it doesn’t account for any light-related conditions that might affect how your eyes react to stimuli.
The pupilometer is non-invasive, which means the patient doesn’t have to undergo any sort of surgery.
The device doesn’t require anesthetics, blood tests, injections, or x-rays. It also doesn’t use CT scans, MRIs or EEGs.
3. Reduction in Manual Entry Errors
The pupilometer is a device that measures the size of the pupil.
This measurement can then assess various conditions, including stress, mental health, and neurological disorders. It has been used for several years, but its use has increased exponentially since it was first introduced. This increase is because this device makes diagnosing patients quicker and less expensive than it would otherwise be without constant manual entry errors made by medical staff or nurses.
The cost of using this technology has also decreased because of improvements in production methods over time, meaning that they are now much cheaper than before.
4. Coma and brain-death determination
The pupilometer can also diagnose coma, brain tumors, and brain injury.
For example, if the pupils are fixed and dilated or non-reactive in response to light (and other stimuli), this can point toward a severe case of coma. Likewise, if the pupils are irregularly shaped or non-reactive in response to light, it can indicate brain tumors. If there is no reflexive reaction when bright lights are shone into the eyes and/or there is a complete loss of consciousness with no eye movement at all, then it may suggest that someone has suffered a traumatic brain injury.
Pupilometer device assists in the diagnosis of neurological disorders.
A pupilometer is a non-invasive diagnostic tool that health professionals can use to measure a patient’s pupils. It can also tell the doctor whether a patient’s pupils are responding normally, so it is valuable for diagnosing traumatic brain injuries.
