The ophthalmoscope (10) has an illumination reproducing optic reproducing illumination beam on an eye (12). A rotating slit diaphragm (18) scans the beam over the eye. An observation reproducing optic reproduces an observation beam produced by a reflection of the illumination beam in the eye on an observation device. Another diaphragm shields scattered light from the observation beam. The device has an electronic sensor (34) with a field of photosensitive pixels, which are activated and/or read. The latter diaphragm has an electronic control circuit to read a pixel line of the sensor.
