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 scanning laser ophthalmoscope (SLO) for imaging the retina of an eye comprises a source (12) of collimated light, a scanning device (14, 16, 1328, 1319), a scan transfer device (20) and a detector (1310). The scan transfer device has a first focus (16) at which an apparent point source is provided and a second focus (24) at which an eye (524, 1324) may be accommodated. The scan transfer device transfers a two-dimensional collimated light scan from the apparent point source into the eye. An optical coherence tomography (OCT) system (900) is combined with the SLO, the OCT system providing OCT reference and sample beams. The OCT sample beam (902) propagates along the same optical path as of the SLO collimated light through the scan transfer device. An aberration compensator (1204, 1316) automatically compensates for systematic aberrations and/or changes in wavefront introduced by scanning elements and the scan transfer device as a function of scan angle.

Abstract: A multi-modal ophthalmic imaging system for acquiring ophthalmic images of a patient's eye comprising: a first imaging module, operable in a first imaging modality, for acquiring a first ophthalmic image of a first portion of the patient's eye and one or more further imaging modules, each operable in a different imaging modality. The imaging system further comprises a control module arranged to: detect an anomaly in the first ophthalmic image that is indicative of an ocular disease, determine a region of interest in the patient's eye based on the detected anomaly wherein the region of interest is a region within the patient's eye that is predicted to contain a second anomaly and determine, based on the second anomaly, a second imaging modality for imaging the determined region of interest and control the selected second imaging module to acquire a second ophthalmic image of the determined region of interest.

Abstract: This disclosure is directed to systems and methods for determining a correction for distortion in eye representations of an ophthalmoscope. A digital model of an optical system including the ophthalmoscope and a model eye may be constructed. The digital model may be transmitted to a ray tracing system. A ray may be passed through the optical system onto a surface of the model eye. A measurement of the ray at the surface of the model eye, with distortion, may be calculated and an angular position of a horizontal scanning element and an angular position of a vertical scanning element can be determined. Using the horizontal scanning angle and vertical scanning angle, a measurement of the ray at the surface of the model eye, without distortion, may be calculated and compared to the measurement with distortion to determine a correction for distortion in eye representations of the ophthalmoscope.
