Retinal treatment

A method of determining control parameters of a retinal treatment system comprising acquiring an image of a retina of a subject's eye using an imaging laser and an optical system of the retinal treatment system, presenting an image of the retina to a user of the retinal treatment system, receiving from the user location data of the retinal image that locates at least one treatment site of the retina, receiving from the user a required laser light pattern for use on the treatment site, using the location data to determine a location control parameter which causes the optical system to direct laser light from a treatment laser of the retinal treatment system to the treatment site, and using the required laser light pattern to determine a pattern control parameter which causes the treatment laser to produce a laser light pattern which passes through the optical system and results in the required laser light pattern at the treatment site.. . ...

Retinal image processing

The disclosure relates to a non-transitory computer-readable storage medium storing computer program instructions which, when executed by a processor, cause the processor to process image data defining an image of a retina to determine a location of an anatomical feature of the retina in the image by receiving the image data; calculating, for each of a plurality of pixels of the image data, a respective local orientation vector indicative of the orientation of any blood vessel present in the image; calculating a normalised local orientation vector for each of the plurality of pixels; operating on an array of accumulators, wherein each accumulator in the array is associated with a respective pixel of the image data; and determining the location of the anatomical feature in the image of the retina using the location of a pixel of the image data which is associated with an accumulator having accumulated an accumulated value.. . ... Optos Plc

Retinal image processing

The present disclosure relates to a computer-readable storage medium storing instructions that can cause a processor to process image data defining an image of a vascular structure of temporal vascular arcades of a retina to estimate a location of the fovea of the retina in the image by transforming received image data such that the vascular structure in the image defined by the transformed image data is more circular than the vascular structure defined by the image data; calculating, for each of a plurality of pixels of the transformed image data, a respective local orientation vector indicative of the orientation of any blood vessel present in the image; calculating a normalised local orientation vector for each of the pixels; operating on an array of accumulators; and estimating the location of the fovea in the image of the retina using the location of a pixel of the transformed image data.. . ... Optos Plc

Ophthalmoscopes

An ophthalmoscope (10) comprising a light source (12), a first scanner (14), a first scan transfer element (16), a second scanner (18), and a second scan transfer element (20), which provide a two-dimensional scan of incident light from an apparent point source at a pupillary point of an eye (22) onto the fundus of the eye, and which descan a two-dimensional scan of return light from the fundus of the eye to provide return light from an apparent point source at the first scanner, wherein the first scan transfer element comprises a free-form element which has a shape defined to provide aberration correction of the return light from the fundus of the eye.. . ... Optos Plc

Imaging of the eye

A method of determining a geometrical measurement of a retina of an eye, comprising obtaining a two dimensional representation of at least a portion of the retina of the eye (34), deriving a geometrical remapping which converts the two dimensional representation of the retinal portion to a three dimensional representation of the retinal portion (36), using one or more coordinates of the two dimensional representation of the retinal portion to define the geometrical measurement to be taken of the retina on the two dimensional representation (38), using the geometrical remapping to convert the or each coordinate of the two dimensional representation of the retinal portion to an equivalent coordinate of the three dimensional representation of the retinal portion (40), and using the or each equivalent coordinate of the three dimensional representation of the retinal portion to determine the geometrical measurement of the retina of the eye (42).. . ... Optos Plc

Ophthalmoscopes

An ophthalmoscope (1) and method for scanning a fundus (23) of an eye (9), comprising a light system (3) which produces linear light, a scanner (5) which receives at least some of the linear light and is movable about a scan axis to produce a 1d scan of the at least some linear light, and a scan transfer system (7) which receives the 1d scan from the scanner and transfers the 1d scan to the eye, wherein the scanner is positioned in the ophthalmoscope such that it receives the at least some of the linear light substantially along the scan axis, the scan transfer system positioned in the ophthalmoscope such that a pupil of the eye is provided at a focal point of the system, and the scanner is positioned in the ophthalmoscope and the scan transfer system is configured to transfer the 1d scan from the scanner through the focal point at the eye pupil and onto the eye fundus.. . ... Optos Plc

Improvements in and relating to imaging of the eye

A method of determining a measurement of at least one cell type in an eye, comprising (i) obtaining a map of the cell type in the eye, (ii) obtaining a representation of the retina of the eye, (iii) matching the eye cell type map to the representation of the retina of the eye, (iv) defining a region of interest on the representation of the retina of the eye, (v) calculating a size of the region of interest on the representation of the retina of the eye, (vi) using the matched eye cell type map and the size of the region of interest to determine a measure of the cell type in the region of interest of the retina of the eye.. . ... Optos Plc

Image processing

The present disclosure provides a method of processing an image comprising receiving a measured image, producing a sharpened image by filtering the measured image to increase its sharpness, and transforming the sharpened image using at least one selected geometric transformation. The present disclosure further provides a computer readable media storing program instructions which, when executed, perform the method of processing an image and a system for processing an image comprising a receiving module which receives a measured image, a sharpening module which produces a sharpened image by filtering the measured image to increase its sharpness, and a transformation module which transforms the sharpened image using at least one selected geometric transformation.. ...
