Nano sensitive study and fractal analysis of segmented retinal layers in Fourier domain OCT: promises for early disease detection

Initial study found that depth-resolved refractive index variations encoded in retinal optical coherence tomography (OCT) exhibits multifractality. Interestingly, automated segmented different layers of the retina exhibited different degree of multifractality in a human eye. In an advanced study, we have adopted nano sensitive study of spectral contents of OCT signals before retinal image construction of a human eye. We have identified and constructed most contributed submicron structural spatial period OCT images. We have quantified nano structural morphological alteration in human retinal layers as deformation progress. This innovative approach promises to develop nano sensitive diagnostic tool for early disease detection in the human eye.
