Abstract
The invention provides an apparatus and method for illuminating, imaging and treating the retina of an eye. The apparatus (10) comprises at least one light source (16), wherein the at least one light source (16) is adapted to provide collimated light (20) from a plurality of point sources (22), and wherein each point source (22) lies on an arc (18), and wherein the at least one light source (16) is configured to direct collimated light (20) from each point source (22) along the radius (24) of the arc (18) towards a center point (26) of the arc (18), and wherein, in use, the apparatus (10) is arranged such that the center point (26) of the arc (18) is substantially coincident with the pupillary point (40) of the eye (14), such that collimated light (20) is transmitted from the point source (22) through the pupillary point (40) of the eye (14) to illuminate the retina (12).
