(54) | SYSTEM AND METHOD FOR IMPROVING SCLERAL SPUR VISIBILITY IN ANTERIOR SEGMENT OCT IMAGES |
(57) 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.
