The invention provides an apparatus and method for illuminating, imaging and treating the retina of an eye. The apparatus () comprises an illuminating device () including a planar light source capable of producing light in a plane, such that the illuminating device () is capable of illuminating a circumferential line on the retina () and a support structure, wherein the illuminating device () is pivotably mountable to the support structure and is rotatable about an axis () which lies substantially on the plane defined by the light source, such that, in use, the illuminating device () may be rotated about the axis () to illuminate an area of the retina ().

Retinal imaging apparatus and method

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 ().

The invention provides an apparatus and method for illuminating, imaging and treating the retina of an eye. The apparatus () comprises at least one light source (), wherein the at least one light source () is adapted to provide collimated light () from a plurality of point sources (), and wherein each point source () lies on an arc (), and wherein the at least one light source () is configured to direct collimated light () from each point source () along the radius () of the arc () towards a center point () of the arc (), and wherein, in use, the apparatus () is arranged such that the center point () of the arc () is substantially coincident with the pupillary point () of the eye (), such that collimated light () is transmitted from the point source () through the pupillary point () of the eye () to illuminate the retina ().
