Which of the following is NOT a parameter in assessing pupils?

In the context of assessing pupils, the parameters typically examined include reactivity to light, size, and accommodation/equality. Reactivity to light refers to how the pupils constrict in response to bright light, which is a critical aspect of neurological assessment. Size is essential as it can indicate various medical conditions or injuries; for example, one pupil may be dilated while the other is constricted, signaling potential issues. Accommodation, or the ability of the pupils to adjust focus between near and far objects, is also an important parameter, alongside ensuring that both pupils are equal in size.

Color, however, is not a standard parameter used in pupil assessment. Pupil color does not change in a way that would impact the assessment of neurological function or health status, making it irrelevant in evaluating pupil response and condition. Therefore, identifying color as not being a parameter aligns with understanding what factors are significant in a clinical assessment of pupils.
