Holmes-Adie syndrome

What it is

A rare ophthalmic disorder characterized by the unilateral or bilateral occurrence of a tonic pupil (showing sectorial denervation of the sphincter pupillae, so that the pupil constricts poorly to light, while the response to near is present but abnormally prolonged), in association with the absence of deep tendon reflexes. In some patients, patchy hypo- or anhidrosis may also be present (a variant known as Ross syndrome). The condition typically occurs in young adults, with a female preponderance.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.
