Mean corneal displacement at normal IOP in an intact cornea. (A) Vertical displacement and (B) lateral displacement in response to 1 mm Hg pressure increase. (C) Vertical displacement and (D) lateral displacement in response to 1 mm Hg pressure decrease. Mean corneal displacement was determined within a pressure range of 15 to 20 mm Hg to improve signal quality. Color unit is µm. A similar displacement was observed in the presence and absence of Bowman's layer.
