A method for visualizing a membrane on a retina of an eye includes recording a first image of the retina of the eye, wherein the membrane on the retina of the eye is not stained, recording a second image of the retina of the eye after the membrane on the retina of the eye has been stained, determining a first transformation such that mutually corresponding structures of the retina of the eye are located at mutually corresponding places in the second image and in the first image which was transformed with the first transformation, identifying image regions in the second image, which contain the membrane on the retina, based on the transformed first image and the recorded second image, and displaying the second image such that the identified image regions in the second image are highlighted relative to the surroundings of the identified image regions.

Method for visualizing a membrane on a retina of an eye and surgical microscope for performing the method

A method for improving an OCT image of an object such as the retina of an eye, using optical coherence tomography by an imaging beam path. In order to suppress shadowing effects due to a surgical instrument moved in the imaging beam path, a time series of OCT images is produced. For an OCT image to be corrected, an area of the object lying in the image and shadowed by the instrument is determined. Another earlier OCT image in which the area of the object is not shadowed is searched in the time series. Image information for the area of the object is read from the earlier OCT image. A corrected OCT image is produced by inserting the read-image information into the OCT image to be corrected, wherein in the OCT image to be corrected, the image information replaces the area of the object which is shadowed by the instrument.
