Adie's tonic pupil, also known as Adie syndrome, is a condition which affects the pupil of the eye. It is caused by damage to the nerves that control the pupil, resulting in the pupil becoming larger than normal. This condition is usually seen in only one eye, however in some cases it can affect both eyes.
Signs and Symptoms of Adie's Tonic Pupil
The most common symptom of Adie's tonic pupil is an abnormally large pupil, which is known as a mydriasis. This can occur in one eye only or both eyes. Other symptoms include reduced or absent pupillary light reflex, and reduced accommodation-convergence reflex.
Diagnosis of Adie's Tonic Pupil
Adie's tonic pupil is usually diagnosed through a careful eye examination. Your doctor will look for an abnormally large pupil, as well as a decreased or absent pupillary light reflex, and reduced accommodation-convergence reflex. Your doctor may order additional tests, such as an electroretinogram (ERG) or electrooculography (EOG), to confirm the diagnosis.
Treatment for Adie's Tonic Pupil
The treatment for Adie's tonic pupil will depend on the severity of the condition. In many cases, the condition may resolve on its own without any treatment. However, if the condition is severe, your doctor may recommend eye drops or other medications to reduce the size of the pupil. Surgery may also be recommended in some cases.
