Consensual Pupillometry for robotic emotional recognition [PDF]
, 2015 The main contribution of this research is to develop of a new measuring device for measuring direct- and consensual light reflex of human pupil. In this case the pupillary light reflex means changing of diameter of pupil due to constant light stimulus as

PLoS ONE, 2019 We evaluated whether the pupillary light reflex is altered in benign essential blepharospasm patients. Twenty-three patients with benign essential blepharospasm, 47 with reflex blepharospasm, and 29 dry eye disease controls were included. Pupillary light

The pupillary light response reveals the focus of covert visual attention. [PDF]
PLoS ONE, 2013 The pupillary light response is often assumed to be a reflex that is not susceptible to cognitive influences. In line with recent converging evidence, we show that this reflexive view is incomplete, and that the pupillary light response is modulated by ...

Pupillometric analysis for assessment of gene therapy in Leber Congenital Amaurosis patients [PDF]
, 2012 Background: Objective techniques to assess the amelioration of vision in patients with impaired visual function are needed to standardize efficacy assessment in gene therapy trials for ocular diseases.

Cortical modulation of pupillary function: systematic review [PDF]
PeerJ, 2019 Background The pupillary light reflex is the main mechanism that regulates the pupillary diameter; it is controlled by the autonomic system and mediated by subcortical pathways.

Melanopsin-expressing retinal ganglion cells are resistant to cell injury, but not always [PDF]
, 2017 Melanopsin retinal ganglion cells (mRGCs) are intrinsically photosensitive RGCs deputed to non-image forming functions of the eye such as synchronization of circadian rhythms to light-dark cycle.

Medical management of hereditary optic neuropathies. [PDF]
, 2014 Hereditary optic neuropathies are diseases affecting the optic nerve. The most common are mitochondrial hereditary optic neuropathies, i.e., the maternally inherited Leber's hereditary optic neuropathy (LHON) and dominant optic atrophy (DOA).

Estimation of operators’ fatigue using optical methods for determination of pupil activity
International Journal of Occupational Medicine and Environmental Health, 2015 Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity.

Pupillary responses to single and sinusoidal light stimuli in diabetic patients
Neurology International, 2009 We examined effects of diabetes mellitus (DM) on the pupillary light reflex (PLR). Phasic pupillary response to a single light stimulus (200 ms) (pPLR) and to continuous sinusoidal stimuli with four different frequencies (0.1, 0.3, 0.7, 1.3Hz) (cPLR ...
