Abstract

Imaging techniques based on spectral changes of oxygenated hemoglobin (HbO2) and reduced hemoglobin (Hb) have been used in humans to measure oxygen saturation in retinal vessels. We have been developed a spectroscopic imaging equipment, consists of a normal fundus camera and two CCD cameras. Oxygen saturation imaging of retinal vessels with a clear difference between arteries and veins has been obtained using a morphological processing and a novel data processing of the line convergence index filter. In this study, high resolution CMOS cameras and a non-mydriatic auto fundus camera were applied to achieve accurate extraction of retinal blood vessels and high resolution imaging of oxygen saturation.
