Abstract
A method of imaging and treating ocular tissue of an eye having a cornea, an iris, an anterior chamber, an irido-corneal angle, and a direction of view includes establishing a common optical path through the cornea and the anterior chamber into the irido-corneal angle for each of an optical coherence tomography (OCT) beam and a laser beam, where the common optical path is offset from an optical axis within the direction of view. The method also includes obtaining a circumferential OCT image of the irido-corneal angle, obtaining an azimuthal OCT image of the irido-corneal angle, and determining a treatment pattern for a volume of ocular tissue of the irido-corneal angle based on the circumferential OCT image and the azimuthal OCT image. The method further includes delivering optical energy through the laser beam in accordance with the treatment pattern.
