DOI: 10.1001/jamaophthalmol.2020.3466
Abstract: Importance Concussion diagnosis remains clinical, without objective diagnostic tests available for adolescents. Known deficits in visual accommodation and autonomic function after concussion make the pupillary light reflex (PLR) a promising target as an objective physiological… read more here.

DOI: 10.1007/s10072-022-05976-2
Abstract: Automated hand-held pupillometry demonstrates precision accuracy, offering promise for augmenting ASD screening. Monocular pupillometry was examined in children and adolescents (36 ASD; 24 TD). Multiple logistic regression and receiver operating characteristic analysis assessed PLR metrics… read more here.
