Illustrating the effect of head tilt on FAZ metrics. Shown on the left is an image from the right eye of a subject (JC_10567) acquired using the patient's normal head posture. The patient was then instructed to tilt the head, after which two additional images were acquired (middle and right panels). The area, axis ratio, and acircularity did not change substantially (less than 3%), whereas the MHAA changed by 44% (middle panel) and 29% (right panel).
