The patient should be supine with the head of the bed elevated 10-15°. Unexpected patient head movement can result in iatrogenic injury, including accidental globe puncture. In patients with altered mental state, taping or restraining the head with help from an assistant may be required. Extremely uncooperative patients may require sedation or, rarely, general anesthesia.
