WebbCONCLUSION. Latency, followed by the constriction velocity, was felt by PICU nurses to be the most important characteristic of the PLR that results in terms “brisk” or “sluggish” being used at the bedside to describe a PLR. We plan to compare these subjective opinions with objective findings from pupillometry. WebbParasympathetic innervation leads to pupillary constriction.

Webb2 aug. 2012 · Bilateral changes in pupil size are generally central in origin. Conversely, anisocoria often suggests a localised event causing constriction (miosis) or dilation (mydriasis) of either pupil.

Webb10 sep. 2024 · Conclusions: Both pupillary constriction and dilatation may occur due to a ciliospinal reflex in patients with brain death. This phenomenon needs further research in …

WebbGenerally, anisocoria is caused by impaired dilation (a sympathetic response) or impaired constriction (a parasympathetic response) of pupils. An injury or lesion in either pathway may result in changes in pupil size. Physiologic (also known as simple or essential) anisocoria is the most common cause of unequal pupil sizes, affecting up to 20% ... WebbTerminology. The pupil is the dark circular opening in the center of the iris and is where light enters the eye. By analogy with a camera, the pupil is equivalent to aperture, whereas the iris is equivalent to the diaphragm.It may be helpful to consider the Pupillary reflex as an 'Iris' reflex, as the iris sphincter and dilator muscles are what can be seen responding …
