Abstract: A method of controlling an ophthalmic device operable to image an imaging region of a retina and concurrently illuminate an illumination region of the retina, the method including acquiring a reference retinal image by imaging a reference imaging area of the retina; designating a target in the reference retinal image; acquiring a current retinal image of an initial imaging region within the reference imaging area; moving the imaging region from the initial imaging region to a destination imaging region using the target and the reference retinal image, and acquiring a retinal image of the destination imaging region; illuminating the illumination region while the imaging region is the destination imaging region; acquiring one or more retinal images while the illumination module is being illuminated; and comparing a marker retinal image based on the one or more retinal image(s) with a comparison image based on the reference retinal image.

Abstract: 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).
