How the Use of Pupillary Size Measurement Is Changing Neurology

The pupillary size measurement is an essential component of the neurologic examination. Health experts can use it to test the integrity of the oculomotor nerve and central nervous system structures such as the brain stem and cerebellum.

  2. Eye tracking is one of the most vital methods by which we can accurately study the human brain. Over the past decade, scientists have found many ways to utilize eye tracking to study neurological diseases, rehabilitation techniques, and much more. Pupillary size measurement is one such technique that is rapidly changing neurology as we know it. This article explains how pupillary measurement can help neurologists diagnose and treat patients with neurological disorders. • ©Copyright by Neuroptics.com

  3. What is Pupillary Size Measurement? Pupillary size measurement is the process of monitoring a person's pupil size to assess neurological functioning. This process is done by measuring the diameter of the pupil's reaction to different stimuli. By measuring how a person's pupils react, we can determine how their nervous system is functioning and any potential problems that may be present. • ©Copyright by Neuroptics.com

  4. What are the various pupillary measurements? Three pupillary measurements are used to determine different neurological functions: Pupil dilation This is the most common pupillary measurement used to determine neurological functioning. For this measurement, the doctor will shine a bright light on one eye to cause the pupil to dilate in response. In normal individuals, both pupils will respond by dilating approximately the same amount. However, in patients with neurological damage, one pupil may dilate more than the other (known as anisocoria). • ©Copyright by Neuroptics.com

  5. Pupil constriction This pupillary measurement is used to assess the function of the parasympathetic nervous system. Constriction happens when the doctor shines a bright light on one eye, causing the pupil to constrict in response. In normal individuals, both pupils will respond by constricting approximately the same amount. Pupillary light reflex Pupillary light reflex is the contraction or dilation of the pupil in response to the illumination of the opposite eye. It is an involuntary brain response mediated by the parasympathetic nervous system. This reflex is used to test a patient's function of the cranial nerves, specifically cranial nerve III (Oculomotor nerve), which innervates pupillary constrictor muscles. Doctors can also use this reflex to test the integrity of the cerebellum and brain stem as ascending pathways run through them. • ©Copyright by Neuroptics.com

  6. Tools for pupillary Measurement in Neurology There are several tools to measure the size of a patient's pupils. The most reliable is the pupilometer. The pupillometer is a hand-held instrument that measures the size of the pupil in millimeters. It uses a light source and magnifying lens to measure the diameter of the pupils in both eyes simultaneously. • ©Copyright by Neuroptics.com
