Abstract: A Fourier-domain OCT apparatus for optoretinography is provided. An example Fourier-domain OCT apparatus comprises: a fixation target which fixes a gaze direction of an eye; an optical system which applies an optical stimulus which is confined to a portion of a retina of the eye whose location is controllable; an OCT imaging system which acquires OCT data from the retina; and a controller which: acquires a target location on the retina; uses the target location to control the optical system, while a position of the fixation target relative to the eye remains fixed, to apply the optical stimulus to a first portion of the retina at the target location; controls the OCT imaging system to acquire OCT data of a second portion of the retina which is stimulated by the applied optical stimulus during acquisition of the OCT data; and generates the ORG data based on the acquired OCT data.

Abstract: A Fourier-domain OCT apparatus for acquiring optoretinography data, comprising: an optical system which applies an optical stimulus to a retina of an eye; an OCT imaging system which acquires OCT data from the retina; and a controller which: controls the OCT imaging system to acquire OCT data of a plurality of portions of the retina such that, for each portion, at least some of the OCT data from the portion is acquired after a respective optical stimulus has been applied to the portion; generates, based on the OCT data, respective ORG data for each portion which indicates the response of the portion to the optical stimulus; and stores respective ORG data generated for each portion in association with a respective position in a visual field of the eye that is optically conjugate with a position of the portion on the retina.

Abstract: A system arranged to process an anterior-segment optical coherence tomography, AS-OCT, image comprising representations of portions of a scleral spur of an eye to obtain a geometric measurement of the eye, comprising data processing hardware arranged to: process the AS-OCT image to acquire respective locations in the AS-OCT image of the representations of the portions of the scleral spur of the eye in the AS-OCT image; and obtain the geometric measurement based on the acquired locations. The system further comprises an OCT imaging system which is operable to acquire the AS-OCT image and comprises a fixation target to fix a gaze direction of the eye during acquisition of the AS-OCT image such that an axis in the AS-OCT image corresponding to a pupillary axis of the eye is aligned with a direction in the AS-OCT image corresponding to an axial imaging direction of the OCT imaging system.
