1. A method for recording and displaying a three-dimensional OCT video, in which OCT volumes of an object region of an observation object are recorded sequentially in time and are combined to form a combined OCT volume, and the combined OCT volume is displayed, the method comprising:
registering a current OCT volume of the OCT volumes recorded sequentially in time;
combining the current OCT volume with a previous combined OCT volume to generate an updated combined OCT volume;
displaying the updated combined OCT volume;
carrying out a check for combining the current OCT volume with the previous combined OCT volume, wherein the check is carried out in respect of which volume regions of the current OCT volume have changed in comparison with corresponding volume regions of the previous combined OCT volume;
combining only the volume regions of the current OCT volume that have not changed with the corresponding volume regions of the previous combined OCT volume; and
replacing the volume regions of the previous combined OCT volume in comparison with which the corresponding volume regions of the current OCT volume have changed by the corresponding volume regions of the newly recorded and registered OCT volume.
