The three-dimensional (3D) mechanical response of the cornea to intraocular pressure (IOP) elevation has not been previously reported. In this study, we use an ultrasound speckle tracking technique to measure the 3D displacements and strains within t

PURPOSE: To formulate an Epithelial Modulation index to differentiate between eyes with contact lens warpage and keratoconus. METHODS: Normal eyes and eyes with either contact lens warpage or keratoconus were scanned by a Fourier-domain optical coher

PURPOSE: To quantify the abnormal corneal thinning and posterior surface steepening that is observed in keratoconus with an Ectasia Index. METHODS: Optical coherence tomography (OCT) was used to image the corneas of normal individuals and patients wi

Characterization of the biomechanical behavior of the optic nerve head (ONH) in response to intraocular pressure (IOP) elevation is important for understanding glaucoma susceptibility. In this study, we aimed to develop and validate a three-dimension

Imaging corneal biomechanical changes or abnormalities is important for better clinical diagnosis and treatment of corneal diseases. We propose a novel ultrasound-based method, called ocular pulse elastography (OPE), to image corneal deformation duri
