Depth-Dependent Corneal Backscatter Characteristics in Different Stages of Keratoconus and a Novel Composite Backscatter Index for Early Detection.
PURPOSE To characterise the depth-dependent distribution of corneal backscatter across keratoconus stages and controls, and to develop a composite Corneal Backscatter Index (CBSI) integrating multi-depth features for early detection of forme fruste keratoconus (FFKC) METHODS: In this retrospective comparative study, 21...
