Abstract
Methods and apparatus are described herein for fluorescent imaging of a retina using a head-mountable device. The retina is illuminated by a head-mountable device (HMD) with light at an excitation wavelength of a fluorophore in the retina and imaged by the HMD at an emission wavelength of the fluorophore. The direction of gaze of a user of the HMD could be determined from the retinal image. The pattern of vasculature in the retinal image could be used to identify the user of the HMD. Information in the retinal image could be used to determine the medical state of the user and diagnose disease states. Fluorescent agents can be introduced into the vasculature of the wearer of the HMD to facilitate these or other applications of fluorescent imaging of the retina using the HMD.
