            What is Holmes-Adie syndrome?

Holmes-Adie syndrome, also known as Adie Syndrome, is a neurological disorder that affects the pupil of the eye and the autonomic nervous system (which controls things that happen automatically in the body, such as heart rate, blood pressure, and digestion).

Holmes-Adie syndrome involves a pupil in one eye that is larger than the other and constricts slowly in bright light as well as the absence of deep tendon reflexes usually in the Achilles tendon (back of calf through heel bone). Both eye and tendon reflex issues may start on one side of the body before progressing to the other side.

Its direct cause is unknown but may involve an infection and damage to nerve cells in the ciliary ganglion, an area of the brain that controls eye movement, and the dorsal root ganglion, an area of the spinal cord that is involved in the autonomic nervous system. People with the syndrome also may sweat excessively; the combination of symptoms is sometimes known as Ross syndrome.

Holmes-Adie syndrome is not life threatening or disabling, but the loss of deep tendon reflexes is permanent. Treatment, if any, may involve reading glasses and eye drops. Surgery to sever the involved sympathetic nerve may reduce excessive sweating.

Learn About Clinical Trials

Clinical trials are studies that allow us to learn more about disorders and improve care. They can help connect patients with new and upcoming treatment options.

How can I or my loved one help improve care for people with Holmes-Adie syndrome?

Consider participating in a clinical trial so clinicians and scientists can learn more about Holmes-Adie syndrome and related disorders. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease.

All types of volunteers are needed—those who are healthy or may have an illness or disease—of all different ages, sexes, races, and ethnicities to ensure that study results apply to as many people as possible, and that treatments will be safe and effective for everyone who will use them.

For information about participating in clinical research visitNIH Clinical Research Trials and You. Learn about clinical trials currently looking for people with Holmes-Adie syndrome atClinicaltrials.gov.
