Paper Abstract

Optical coherence tomography (OCT) has revolutionized diagnostics in ophthalmology. However, OCT traditionally requires an operator and patient cooperation to align a scanner with the subject’s eye and image a specific location of the retina. We have developed a robot-mounted OCT scanner that automatically aligns with the subjects’ eye by compensating motion and gaze. In addition to using face and pupil tracking feedback to align the scanner, the system uses gaze feedback to track a retinal region of interest, such as the fovea. We demonstrate our system by tracking the fovea of human eyes subject to physiological motion and gaze change.
