An exam under anesthesia (EUA) is an examination of a patient while he or she is under anesthesia. In this case, the exam is performed on the eyes.
The doctor orders an EUA when a patient is unable to tolerate a complete eye exam within an outpatient clinic setting. This may be due to the patient's age, developmental level or level of cooperation. An EUA is performed in the operating room while the patient is under general anesthesia.
