The invention provides an apparatus and method for scanning, imaging and treating the retina of an eye. The apparatus () comprises a source of collimated light (), a two-dimensional scanning device () having two axes of rotation (), wherein the axes of rotation () are orthogonal and substantially planar, and wherein the source of collimated light () and the two-dimensional scanning device () combine to provide a two-dimensional collimated light scan from a point source (). The apparatus () further comprises a scan transfer device (), wherein the scan transfer device () has two foci () and the point source () is provided at a first focus point () of the scan transfer device () and an eye () is accommodated at a second focus point () of the scan transfer device (), and wherein the scan transfer device () transfers the two-dimensional collimated light scan from the point source () into the eye ().

Retinal imaging apparatus and method

The present invention provides a scanning ophthalmoscope for scanning the retina of an eye and a method of scanning the retina of an eye. The ophthalmoscope () comprises a source of collimated light (), a first scanning element (), a second scanning element () and a scan relay device () having two foci (). The source of collimated light (), the first and second scanning elements () and the scan relay device () combine to provide a two-dimensional collimated light scan () from an apparent point source (). The scanning ophthalmoscope () further comprises a scan transfer device (), wherein the scan transfer device () has two foci () and at least one vertex () and the apparent point source () is provided at a first focus () of the scan transfer device () and an eye () is accommodated at a second focus () of the scan transfer device (), and wherein the scan transfer device () transfers the two-dimensional collimated light scan () from the apparent point source () into the eye (). The two foci () of the scan relay device () and the two foci () of the scan transfer device () define a first plane and the two foci () and the at least one vertex () of the scan transfer device () define a second plane and wherein the first and second planes are substantially parallel.
