the pupil of the eye
Inequality in pupil size, known as anisocoria, can be due to variations in sympathetic and parasympathetic nerve activity in each eye. This can be caused by conditions such as Horner's syndrome, brain injury, or certain medications. It is important to consult with a healthcare professional for a proper evaluation and diagnosis.

Eye trauma can damage the muscle that controls pupil size.
size of pupil becomes larger when you see in dim light
The iris, specifically the muscles within it, control the size of the pupil. Contraction and relaxation of these muscles regulate the amount of light entering the eye by adjusting the diameter of the pupil.
No. The pupil can only open to the size of the iris.
The iris is the layer that surrounds the pupil and controls the size and diameter of the pupil. It also controls the amount of light that reaches the pupil.
YES
The pupil size is controlled by the iris muscles. In bright light, the iris constricts the pupil to reduce the amount of light entering the eye. In dim light, the iris dilates the pupil to allow more light to enter. Emotional responses or changes in focus can also affect pupil size.
In the Glasgow Coma Scale, pupil size is typically observed before applying light stimulation. This is done to assess the initial baseline size of the pupil before assessing how it reacts to light, which is an important indicator of neurological function.
Nothing. AFTER the light is detected and calibrated, the pupil may change size.
