ABSTRACT:
A fundus camera is provided with auxiliary optical components and a plurality of projected alignment marks, wherein the alignment marks are in focus and coincident on the iris of the eye when the fundus camera is correctly aligned and the auxiliary optical components allow the alignment marks to be observed as an anterior view in focus, replacing part of the view of the eye fundus which is also in focus in the same view. The auxiliary view optical components may be linked to the focus of the observation system and the associated projected focus indicating marks such that all remain in adequate focus to enable the alignment and focus of the fundus camera to be performed satisfactorily.
