Summary
To investigate the variation in backscattering with depth between forme fruste keratoconus (FFKC), keratoconus, and normal eyes; to determine the backscattering changes in the characteristics of keratoconus progression; and to explore the diagnostic value of backscattering in FFKC.
Detailed description
To investigate the variation in backscattering with depth between forme fruste keratoconus (FFKC), keratoconus, and normal eyes; to determine the backscattering changes in the characteristics of keratoconus progression; and to explore the diagnostic value of backscattering in FFKC. A Scheimpflug corneal tomography image and caliper tool were used to obtain backscatter at every 2% depth at the thinnest point of the cornea, with the measured values expressed in grayscale units (GSU).
