Question: 1 / 400

What is indicated by a mydriatic pupillary reaction?

Pinpoint pupils

One pupil larger than the other

Enlarged pupils

A mydriatic pupillary reaction is characterized by enlarged pupils, or mydriasis. This condition can occur as a result of various factors, such as exposure to certain drugs, physiological responses to low light, or neurological conditions. When pupils are enlarged, it indicates that the muscles controlling the pupil's size are relaxed, allowing more light to enter the eye. This reaction can be a physiological response to low-light environments or could indicate the influence of specific medications or substances that stimulate dilation.

In contrast, pinpoint pupils would suggest a different condition, such as opioid use or certain neurological disorders. Having one pupil larger than the other points to a potential issue with the nervous system or an eye injury, known as anisocoria. Normal pupil size would indicate that there are no abnormalities present, which does not apply in this case of mydriasis.
