Indentation UBM on an eye with a plateau iris. The angle is slit-like opened (the arrow represents the scleral spur location). The “double-hump” sign, one hump owing to the ciliary process (black arrow head) and the other owing to the lens (white arrow head), is demonstrated. (Adapted from Ishikawa H, Inazumi K, Liebmann JM, Ritch R. Inadvertant corneal indentation can cause artifactitious widening of the iridocorneal angle on ultrasound biomicroscopy.
