A combined fundus scanning apparatus for optical coherence tomography (OCT) and fundus imaging has an OCT unit (1) with a first light source creating a point-shaped scanning beam, an interferometer with a first sensor for sensing and evaluating the beam reflected by the retina (8), an imaging device (14), which focuses the scanning beam onto the retina (8) of an eye (9) to be examined, as well as a first beam deflection unit (4) to move the scanning beam in the X direction and a second beam deflection unit (11) to move the beam in the Y direction across the retina (8). Fundus imaging is effected by means of a second light source (5) that emits light of a spectral range different from the first light source, which light is also imaged onto the retina (8) via the imaging device (14), and which impinges on a second sensor (10) for sensing the light of the second light source (5) reflected by the retina (8). The second light source (5) is configured as a line light source, and the second sensor (10) is a line sensor. The light of the second light source (5) passes through one of beam deflection units (4, 11) to be moved by it across the retina (8). |
