The abnormal pupil. Part 2: Causes and management of anisocoria Academic Article uri icon


  • Anisocoria may be a sign of impending neurological disaster and recognition is therefore crucial. However, in many cases there are no sinister implications. It is important to be able to recognise the difference in order to spare the patient unnecessary investigations and, conversely, to act promptly and effectively when a true emergency is looming. Last month, Part 1 of this article discussed the clinical examination of patients with abnormal pupils and the management of a variety of causes; now, Part 2 outlines the diagnosis and treatment of the different types of anisocoria.
