Non-contact optical coherence tomography imaging of the central and peripheral retina
Abstract:
A system includes a mirror having an axis extending through a central portion thereof, and a portion of the mirror being configured to repeatedly oscillate between a first position and a second position around the axis, so as to record a field of up to 200 degrees of a portion of the central and peripheral retina, a first scanner configured to use a spectral domain optical coherence tomography system to obtain a non-contact wide angle optical coherence tomography-image of the portion of the central and peripheral retina, and a second scanner configured to obtain an image of the retina, wherein the mirror is configured to oscillate so as to move the focal point of the mirror from one side of a pupil to another side, thereby permitting scanning light inside the eye to cover a predetermined peripheral field, thus creating a two dimensional or three dimensional image of the field.
