Abstract
When the MTF is computed from double-pass (DP) retinal images, the modulation transfer function (MTF) presents typically a peak at zero frequency provoked by the constant background illumination that affects the point spread function (PSF) of the eye. Under conventional DP data processing, this peak is avoided by extrapolating the zero frequency from a curve fitting. In this work, we use the information removed by the peak correction process to estimate intraocular scattering by introducing an i...
