pupillometry
Pronunciation: pyoo-pi-LOM-uh-tree
Automated measurement of pupil size and reactivity using specialized devices for neurological assessment.
Full Definition
Pupillometry is the quantitative assessment of pupil size, shape, and light reactivity using automated devices rather than manual penlight examination. In neurocritical care, it provides objective measurements of pupillary responses that can detect subtle changes in intracranial pressure or brainstem function. Modern pupillometers calculate the Neurological Pupil index (NPi) to standardize assessments across healthcare providers.
