Cerebral herniation due to brain edema is the major cause of neurological worsening in patients suffering large hemispheric strokes. In this study, we investigated whether quantitative pupillary response could help identify the neurological worsening due to brain swelling in patients with large hemispheric strokes. ⋯ Quantitative monitoring of the pupillary response using an automated pupillometer could be a useful and noninvasive tool for detecting neurological deterioration due to cerebral edema in large hemispheric stroke patients.
