WebbGenerally, anisocoria is caused by impaired dilation (a sympathetic response) or impaired constriction (a parasympathetic response) of pupils.

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.
