(ie, accommodation), whereas increased sympathetic nerve activity results in contraction of the pupil dilator muscle causing pupil dilation.23 The mechanism behind the parasympathetic stimulation by caffeine is that it competitively binds to adenosine receptors,23 resulting in the rise in levels of ...

velocities. First and second dilation velocities are evaluated because a pupil generally will dilate quickly for a first period of time and, thereafter, will dilate more slowly until its original size and configuration are achieved. Finally, as explained above, an analysis object 108 in accordance ...
size, center and diameter. However, due to the gray level of eyelash and pupilare close, not only pupil but also eyelash are existed in the binary image. Only avoidthe eyelashes can find the real pupil contour. In pupil detection, the morphologicalmethods such as erosion and dilation are ...
(<21 mmHg) before dilation and after testing. All participants had normal colour vision as assessed by the Farnsworth D-15. Participants with implanted intra-ocular lenses, medications known to affect pupil size, and other diseases that can affect ipRGC function, including diabetes, were ...
nerve activity could account for contraction of the ciliary body and relaxation of the zonules, resulting in increased convexity of the crystalline lens (ie, accommodation), whereas increased sympathetic nerve activity results in contraction of the pupil dilator muscle causing pupil dilation.23...
