Importance of Pupil Diameter Measurement in Treating Brain Injury

Importance of Pupil Diameter Measurement in Treating Brain Injury

Neuroptics targets the critical care units and performs Pupillary evaluation as a noninvasive and rapid test that offers an indication of the nervous system and eye health. The pupil diameter measurement is essential as the pupils tend to be smaller due to pupillary light reflex.

Acute pupillary dilation may occur in in a head-injured patient. The treatment of which is a neurological emergency. The dilation occurs due to herniation and brain stem compromise, which may cause mechanical compression of the cranial nerve.

Several researchers have used the pupilometer for pupil evaluation and assessed the functioning of the autonomic nervous system. It helps observe drug injury and fatigue, gauge the metabolism of drugs, and numerous other applications in both human beings and animals.

The device is extremely beneficial for patients with traumatic brain injury. It helps conduct a neurological assessment, i.e., the inspection of motor response and sensory neurons. The clinical assistant helps neurologists examine the nervous system.

The Iris size or pupillary diameter is controlled by two muscles, namely the sphincter pupillae and the dilator pupillae. The first one is under the control of the parasympathetic nervous system, while the latter functions under the control of the sympathetic nervous system.

People suffer from focusing their eyes or encounter double vision after a traumatic brain injury.

The pupil goes through several transformations due to increased internal pressure. A proper pupil evaluation helps treat brain injury. Apart from measuring pupillary response and size, a pupilometer evaluates the pupillary response in traumatic brain injury.

Researchers have shown when people hear someone laugh or cry, and their pupils become enlarged. Sometimes, your pupils get larger if you undergo some emotional reaction.

NeurOptics pupilometer helps determine the refractive correction. The tool is used in ICUs to treat severely ill neurological patients.

The Final Takeaway An injury in the third cranial nerve or the upper brain stem may give rise to a unilateral fixed dilated pupil. Pupillary evaluation is a rapid, noninvasive test that assesses the eye health and nervous system.
