Pupillary Light Reflex Variability as a Predictor of Clinical Outcomes in Subarachnoid Hemorrhage.
A change in the pupillary light reflex (PLR) is a sensitive indicator for detecting expanding intracranial lesions. Changes in PLR may be a prognostic marker for patients with intracranial lesions. The purpose of this analysis was to explore how PLR readings, size, constriction velocity (CV), dilation velocity (DV), Neurologic Pupil Index (NPi), and latency predict clinical outcome in patients with subarachnoid hemorrhage. ⋯ Patients with higher WSD PLR values showed better outcomes (ie, lower mRS at discharge), suggesting that patients with narrower WSD PLR are at a higher risk for poor outcomes.
