Corneal biomechanical properties in myopic eyes evaluated via Scheimpflug imaging

BMC Ophthalmology, 2020
Background To investigate the biomechanical properties of the cornea in myopic eyes using corneal visualization Scheimpflug technology (Corvis ST). The relationships between the biomechanical properties of the cornea and the degree of myopia were also ...

Keratoconus Detection Based on a Single Scheimpflug Image

Translational Vision Science & Technology, 2020
To introduce a new approach for keratoconus detection based on corneal microstructure observed in vivo derived from a single Scheimpflug image.Scheimpflug single-image snapshots from 25 control subjects and 25 keratoconus eyes were analyzed; from each group, five subjects were randomly selected to provide out-of-sample data.
