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 Fourier-domain optical coherence tomography imaging system (10) comprising an Fourier-domain optical coherence tomography scanner (20) arranged to generate complex optical coherence tomography data (25) by performing a scan of an imaging target (30) to acquire samples whose complex values are indicative of an optical property of the imaging target at respective scan locations in the imaging target. The imaging system (10) further comprises a controller (40) arranged to calculate a two-dimensional cross-correlation using phase information of the acquired samples, and control the scanner (20), based on the calculated cross-correlation, to compensate for relative movement between the imaging target (30) and the scanner (20) during the scan.

Abstract: An optical assembly for optically coupling a light source and a photodetector to an optical system of an ophthalmic imaging apparatus, the optical assembly comprising: a housing through which a light beam from the light source propagates towards the optical system along an optical path, and light from an eye collected by the optical system propagates towards the photodetector along the optical path; an arm which extends into the housing and supports a reflective surface to reflect the light beam towards the optical system; and an adjustable mechanism attaching the arm to the housing and allowing the reflective surface to be adjusted by: rotation about a first axis passing through a point on the reflective surface and perpendicular to the optical path; rotation about a second axis passing through the point and perpendicular to the first axis and the optical path; and/or translation along the optical path.

Abstract: Aspects of the present invention relate to a method of detecting clipping of retinal image content in an optical coherence tomography, OCT, image of a patient’s retina. The method comprises detecting a boundary of the retinal image content in the OCT image and calculating a distance between the boundary and an edge of the OCT image. The method further comprises determining if clipping of the retinal image content in the OCT image has occurred by comparing the calculated distance between the boundary and the edge of the OCT image with a clipping threshold distance. Clipping of the retinal image content is determined to have occurred when the calculated distance between the boundary and the edge of the OCT image is equal to, or less than, the clipping threshold distance.

Abstract: Aspects of the present invention relate to an ophthalmic imaging system for imaging a target on a posterior segment of a patient's eye, the imaging system comprising: a light source configured to emit a light beam for imaging the target; an imaging device for tracking a position of an anterior segment of the patient's eye; and a controller configured to determine a movement of the target in dependence on the tracked position of the anterior segment of the patient's eye; wherein the controller is further configured to adjust an angle of incidence of the light beam that contacts the posterior segment in dependence on the determined movement of the target.

Abstract: An ophthalmic device includes a scanning member, an objective lens, and an optical element. The objective lens includes a first lens group and a second lens group in order from the scanning member side. The optical element is capable of being inserted into and removed from an optical path between the second lens group of the objective lens and the scanning member. In a case in which the optical element is not inserted into the optical path, the objective lens configures a first observation optical system. In a case in which the optical element has been inserted into the optical path, the objective lens and the optical element configure a second observation optical system.
