The pupillary light response (PLR) and a task evoked pupillary response (TEPR) were used to test this hypothesis in same-aged patients with early onset (EOET) and late onset (LOET) essential tremor and healthy controls.Becktepe, Jos S.Goevert, FelixKasiske, LisaYalaz, MevluetWitt, ...
Pupillary response The pupillary response is subserved by two cranial nerves, II (afferent) and III (efferent). Test this response in children from all three age groups by moving a focused flashlight beam onto the pupil from the side; as the light is then moved to the other pupil, look...
Influences of unseen light at the BS on the PLR To test whether the difference in the magnitude of the PLR between the red and white stimuli was repeatable without perceptual filling-in, we created a new stimulus. At the same time as the small disk stimulus was presented inside the BS, ...

Light Response Pupil Test A light will be shone into your eyes from each side. Your practitioner willwatch your pupils closely to determine whether or not your pupilsconstrict in response to the light, making note of the size and shape of your pupils. ...
All subjects com- pleted the chromatic pupillometry test during the daytime between 8:30 am and 5:00 pm. To assess the amplitude of pupillary constriction, the pupil diameter was expressed as a percentage of the dark pupil prior to light expo- sure. The median constriction response was ...
As a secondary aim, we also sought to examine how pupillary responses to people of sexual interest are affected by image luminance. The pupils constrict in response to light (i.e., increased luminance) to protect the cells of the retina (Bergamin & Kardon,2003; Ellis,1981). If this diffe...
attributed to the light reflex, may be an immediate and spontaneous response to the detection ofanybiologically significant sexual cue. Later pupil dilation (sympathetically controlled) occurring after the initial 400 ms period may relate to stimulus content and sexual orientation (Finke et al.,2017)...
The pupillary light reflex is of great importance and should be examined next. As bright a light source as possible should be used in dim surroundings. First, it must be established that there is a direct and consensual response to light in each eye. In severe visual loss, the amplitude ...
If TPP1 infused into the CSF can reach the tissues involved in retinal-mediated light responses, this treatment may preserve visual function as well. Quantitative evaluation of the pupillary light reflex (PLR) in conjunction with electroretinogram (ERG) assessment is a sensitive tool to evaluate ...
