Abstract
The invention relates to a method for photographically observing and/or documenting the fundus of an eye, comprising: producing a lighting beam path by means of a lighting module for lighting at least one partial area of the fundus by using an at least approximately punctiform or at least areally limited lighting source, producing an image plane in the lighting beam path for the creation of photographic recordings, separating the pupil cross-sectional area into a detectable observation region and an undetectable lighting region, producing an image area that contains the image of the fundus on the image plane, dividing the image area in strips in the lighting beam path into a lighted region and unlighted regions, and imaging the third and fourth Purkinje reflection on the image area, wherein at least one Purkinje reflection, the third and/or fourth Purkinje reflection, is located in the unlighted regions of the image area.
