Abstract
Background: Adie’s Tonic Pupil is a condition of a tonically dilated pupil, which is unresponsive to bright light followed by moderate responsiveness to accommodation. This condition will resolve with time, ranging from months to years. Some patients may experience increased accommodation for near vision but the pupillary light response does not recover and become persistent after 2 years.
Case Presentation: A 26-year-old female patient showed anisocoric pupil in a response to bright light in the left eye. The size of the pupil is 7 mm with the absence of direct and indirect light reflexes and near reflexes. She was diagnosed with Adie’s tonic pupil. It is found to be persistent in the 3 years of follow up, the involved pupil was showing anisocoria, 5 mm in diameter, poor constriction mechanism in direct, indirect, and near reflexes examinations.
Conclusion: Adie’s tonic pupil is a benign neuro-ophthalmology disorder of unknown etiology. This condition mostly will spontaneously resolve. But, at some patients, it could be persistent, which may be related to degree of myelination of neural fibers.
