Adie's Pupil

Adie's Pupil (pronounced: AY-deez PYOO-puhl), also known as Adie's Tonic Pupil or Holmes-Adie Syndrome, is a neurological condition characterized by a pupil that reacts slowly to light but has a more normal and quicker response to accommodation (focusing on near objects).

Etymology

The condition is named after the British neurologist, William John Adie, who first described it in 1931.

Symptoms

The primary symptom of Adie's Pupil is an abnormally large pupil (mydriasis) that reacts slowly to light but responds more quickly to accommodation. Other symptoms may include blurred vision, difficulty reading, and sensitivity to light. In some cases, the condition may also be associated with absent or diminished deep tendon reflexes, a condition known as Adie's Syndrome.

Diagnosis

Diagnosis of Adie's Pupil is typically based on the clinical presentation and a detailed eye examination. The use of a slit lamp examination can help to identify the characteristic light-near dissociation of the pupil. In some cases, pharmacological testing with a dilute solution of pilocarpine can also be used to confirm the diagnosis.

Treatment

Treatment for Adie's Pupil is usually not necessary unless the symptoms are causing significant discomfort or functional impairment. In such cases, treatment options may include the use of corrective lenses to improve near vision or the use of pilocarpine eye drops to constrict the pupil and reduce light sensitivity.
