How can you describe the typical presentation of Horner's Syndrome?

The typical presentation of Horner's Syndrome is characterized by classic findings of ptosis and pupillary mitosis. Ptosis refers to the drooping of the upper eyelid, while pupillary mitosis denotes constriction of the pupil on the affected side. This condition arises from disruption of the sympathetic pathways that innervate the eye.

In Horner's Syndrome, the combination of these signs results from a loss of sympathetic innervation, leading to a noticeable difference between the affected side and the normal side. The constriction of the pupil occurs because the parasympathetic tone is more prominent when sympathetic input is reduced. Additionally, the ptosis occurs due to weakness of the muscle that elevates the eyelid, further indicating the impact of disrupted sympathetic pathways.

Other symptoms that may be associated with Horner's Syndrome could include anhidrosis (lack of sweating) on the affected side of the face, but the core and defining signs that are most commonly recognized are indeed ptosis and pupillary mitosis, making this choice the most accurate description of the syndrome’s typical presentation.
