Nystagmus is a condition that causes involuntary eye movements. It can be a sign of a variety of underlying medical conditions, including neurological disorders, eye problems, and drug or alcohol use. Checking for nystagmus is a simple procedure that can be performed by a healthcare professional.
To check for nystagmus, the healthcare professional will ask the patient to look straight ahead. The healthcare professional will then move an object, such as a pen or finger, in front of the patient’s eyes. The healthcare professional will observe the patient’s eyes for any involuntary movements.
