abstract="The pupillary light reflex (PLR) reflects physiologic arousal, and a potential point-of-care biomarker of suicide risk. We collected data from 9 healthy controls, 6 non-suicidal depressed patients, 7 with prior suicide attempts but not presently suicidal, and 8 depressed patients who were actively suicidal. The pupillary maximum constriction velocity (MCV) was similar between the non-suicidal depressed patients and healthy controls (the &quot;Never suicidal&quot; group). Patients with prior attempt resembled the patients expressing active suicidal ideation (the &quot;Ever suicidal&quot; group). MCV was a significant predictor within a logistic regression model of participants who were &quot;Ever suicidal&quot; versus &quot;Never suicidal&quot;.<p /> <p>Language: en</p>",
