Abstract
A numerical method to compensate retinal shadows in choroid is presented. The averaged A-scans beneath retinal vessels and A-scans surrounded by them are calculated. The effect of absorption is estimated by subtracting those A-scans. By adding that offset value to A-scans beneath the retinal vessels, the shadows in the choroid are compensated. In vivo imaging of human eye was performed by 840 nm band standard resolution spectral domain optical coherence tomography and choroidal vasculature projection images were calculated. The removal of retinal shadows improves the readability of choroidal images.
