'Pupillary dilation'(瞳孔扩大)和'pupillary constriction'(瞳孔缩小)是医学检查中常用的术语,分别指瞳孔的开大和缩小反应,这些反应对于评估自主神经系统功能、药物效果及疾病状态具有重要意义。此外,'pupillary light reflex'(瞳孔对光反射)是评估视觉通路完整性的重要指标之一,它反映了光线刺激下...

In pupillary dilation the anterior surface of the iris is made up of a mass of circumferentially-oriented blood vessels bulging prominently into the anterior chamber. In pupillary constriction the blood vessels are stretched out. They zig-zag from the periphery of the iris towards the pupillary...
As an additional analysis of the fNIRS data, a repeated measures ANOVA with hemisphere (left, right), race (own, other), and pupil (constriction, dilation) as within-subject factors was conducted in an additional brain region, the temporal parietal cortex (TPC). This brain region was ...

Contraction of the sphincter, accompanied by relaxation of the dilator, produces pupil constriction (miosis); while contraction of the dilator, accompanied by relaxation of the sphincter, produces pupil dilation (mydriasis). These muscles are innervated by the autonomic nervous system and controlled by...

Rather, the pupil diameter increased slightly and this pupil dilation developed gradually without clear latency locked to the stimulus onset (see Fig. 2a,“small disk” at “BS”). This effect could be attributed to autonomic responses mediated by arousal signals conveyed by sympathetic nerves, ...
When intracranial pressure was elevated, the Neurologic Pupil index, percent change in pupillary size, constriction velocity, and dilation velocity were significantly lower than when intracranial pressure was within normal range (p < 0.001 for all). There were mild to moderate negative correlations ...
Pupil diameter is determined by two antagonistic smooth muscle groups, the sphincter and dilator muscles within the iris. Pupillary constriction or miosis is brought about by the action of the sphincter muscle, whereas pupillary dilation or mydriasis happens by the contraction of the dilator muscle...
