1. System for imaging a volume portion of an eye, the system comprising: an optical microscopic apparatus; and an OCT-imaging apparatus, wherein the optical microscopic apparatus comprises: a light source for illuminating a part of the eye; an imaging optics for imaging the illuminated part of the eye to an image plane of the imaging optics; a spatially resolving detector arranged in the image plane for acquiring an optical microscopic image of the part of the eye; and an image processing system for analyzing the acquired optical microscopic image, wherein the analyzing comprises identifying at least one distinguishable anatomical structure in the optical microscopic image based on the optical microscopic image and at least one reference image comprised in a data storage to predict a location of the volume portion; wherein the OCT-imaging apparatus comprises: a beam source for generating a measurement beam and a reference beam; an OCT-controlling system for directing the measurement beam merely to the volume portion using the predicted location of the volume portion; an interferometer for interferometrically superimposing the reference beam with a light beam emanating from the volume portion; a detector for detecting the interferometrically superimposed light beams; and a data processor system for computing a representation of the volume portion based on the detected superimposed light beams.
