Horner's is a malfunctioning of the sympathetic innervation to the pupil. Depending on what drug is used to dilate the pupil, and where the malfunction is, it could do.
Eye disorders that result in pupils that do not dilate can include Adie's tonic pupil, where one pupil is larger and reacts poorly to light, and Horner's syndrome, characterized by a constricted pupil on the affected side. Other conditions, such as certain types of glaucoma or damage to the optic nerve, can also lead to non-reactive pupils. Anisocoria, or unequal pupil size, may also present with one pupil that does not dilate properly. These conditions can indicate underlying neurological or pathological issues and typically require medical evaluation.
Yes, you can see your pupil get bigger (dilate) and smaller (contract) in response to changes in lighting conditions. The pupil dilates to allow more light into the eye in dim environments and contracts to restrict the amount of light entering the eye in bright environments.
The iris controls the amount of light that is entering the pupil. When its dark out, the sphincter muscles on the iris ease to dilate the pupil, but when its light out, the sphincter muscles contract to constrict the opening of the pupil.
The pupil is the part of the eye that regulates the amount of light that enters. It can dilate to let in more light in dim conditions and constrict to reduce the amount of light in bright conditions. This is controlled by the iris, a circular muscle that surrounds the pupil.
