Abstract: A method of method of processing optical coherence tomography, OCT, image data representing an OCT image of a retina of an eye, to generate mapping data which maps out a predetermined band of a plurality of distinct bands which extend across the OCT image and correspond to respective anatomical layers of the retina. The method comprises: receiving the OCT image data; processing A-scan data of the received OCT image data to generate data indicative of sequences of A-scan elements corresponding to the predetermined band of the plurality of distinct bands and having respective A-scan element values that vary in accordance with a predetermined pattern; and generating the mapping data by applying a line-finding algorithm to determine a line passing through the sequences of A-scan elements indicated by the generated data.

Abstract: A computer-implemented method of searching for a region indicative of a pathology in an image of a portion of an eye acquired by an ocular imaging system, the method comprising: receiving image data defining the image; searching for the region in the image by processing the received image data using a learning algorithm; and in case a region in the image that is indicative of the pathology is found: determining a location of the region in the image; generating an instruction for an eye measurement apparatus to perform a measurement on the portion of the eye to generate measurement data, using a reference point based on the determined location for setting a location of the measurement on the portion of the eye; and receiving the measurement data from the eye measurement apparatus.

Abstract: A method of processing B-scans acquired by an OCT imaging system to generate correction data for compensating for axial displacements between B-scans caused by a variation in distance between the OCT imaging system and an imaging target, and to generate a reliability indicator indicative of a reliability of the correction data. The correction data is generated by determining, for each pair of adjacent B-scans, a respective indicator of an axial shift between respective representations of a common ocular feature in the adjacent B-scans. The reliability indicator is generated by: calculating values indicative of speeds or accelerations of the imaging target relative to the OCT imaging system when pairs of B-scans were acquired; where at least a predetermined number of calculated values exceed a threshold, setting the reliability indictor to indicate that the correction data is unreliable, and otherwise to indicate that the correction data is reliable.

Abstract: An ophthalmic device comprising a light source to emit fixation target light, and a reflecting face to reflect scanning light emitted by an emission section and scan the scanning light in a specific direction by changing orientation, the emission section being a scanning light source different to the light source. A concave mirror face is disposed so scanning light reflected by the reflecting face is incident on a subject's eye ocular fundus when the eye is at the concave mirror's focal point, and is arranged such that, when the eye is at the concave mirror's focal point, and when the light source emits fixation target light, that light and scanning light are simultaneously incident on the ocular fundus via different optical paths propagating via the concave mirror face and focal point, the target fixation light following a predetermined optical path for fixing the subject's eye gaze.

Abstract: An optical system, capable to admit a light beam, the optical system comprising: a plurality of reflectors configured to reflect the light beam, wherein each of the reflectors is configured to reflect an incident light beam such that the path of the incident light beam and the path of the reflected light beam are parallel to each other. Each of the reflectors has a reflection center axis positioned centrally between the path of the incident light beam and the path of the reflected light beam. At least two of the reflectors are arranged relative to each other such that their respective reflection center axes do not overlap, thereby enabling the path of the light beam to pass at least one of the at least two of the reflectors multiple times.

Abstract: Apparatus for illuminating the retina of an eye. The apparatus includes an illumination device and a lens system. The illumination device and the lens system combine to provide incident illumination from an apparent point source located within the lens system. The apparatus also includes an illumination transfer device. The illumination transfer device has two foci and the apparent point source of the lens system is provided at a first focus point of the illumination transfer device and an eye is accommodated at a second focus point of the illumination transfer device. The illumination transfer device transfers the incident illumination from the apparent point source into the eye to illuminate the retina.
