Acute monosymptomatic anisocoria after removing a scopolamine patch from a patient Acute anisocoria requires timely examination to rule out intracranial pathology. This case report describes a 34-year-old nurse who experienced blurred vision and unilateral mydriasis. She had no other complaints, and neurological examinations were normal. Shortly before, she had removed a scopolamine (hyoscine) patch from a patient and had following inadvertently rubbed her eye. The symptoms remitted completely within 24 hours. Knowledge of this benign phenomenon is important in order to advise patients and caregivers when handling a scopolamine patch, and in order to avoid unnecessary investigations.
