What are the latest advances in Holmes-Adie Syndrome?

Holmes-Adie Syndrome is a rare neurological disorder characterized by a tonic, poorly reactive pupil and diminished deep tendon reflexes. While there is currently no cure, recent research focuses on refining diagnostic imaging and understanding the underlying autonomic dysfunction to better manage symptoms for the 53 members of our DiseaseMaps community and others living with the condition.

What are the current research directions for Holmes-Adie Syndrome?

Modern research into Holmes-Adie Syndrome has shifted toward advanced neuroimaging to distinguish it from other pupillotonic disorders. Investigators are increasingly using high-resolution ultrasound and optical coherence tomography (OCT) to observe the structural changes in the ciliary ganglion. By better mapping the post-ganglionic cholinergic denervation that defines Holmes-Adie Syndrome, researchers hope to improve diagnostic accuracy and reduce the need for invasive testing.

Are there new diagnostic tools or biomarkers for Holmes-Adie Syndrome?

Precision medicine is beginning to influence how we approach Holmes-Adie Syndrome. Current efforts include:

• Refining pharmacological testing using dilute pilocarpine (0.125%) to confirm denervation hypersensitivity.


• Utilizing infrared pupillometry to provide objective, standardized measurements of pupil response.


• Investigating systemic autonomic biomarkers to determine if Holmes-Adie Syndrome is part of a broader dysautonomia spectrum in specific patient subsets.

How are clinical trials and treatments evolving?

While Holmes-Adie Syndrome is generally considered a benign, non-progressive condition, clinical attention is focused on symptomatic relief. There are currently no gene therapies or biologics for Holmes-Adie Syndrome, as the focus remains on conservative management, such as the use of reading glasses or low-dose pilocarpine drops for those bothered by photophobia or blurred vision. Research remains limited, and most clinical trials for related autonomic neuropathies are in early-stage observational phases.

Next steps

• Consult a neuro-ophthalmologist to confirm your diagnosis through standardized pupillary testing.


• Visit ClinicalTrials.gov and search for "Adie's Pupil" or "Autonomic Neuropathy" to identify observational studies.
