To compare quality and usability of images taken by two different camera-systems without dilating the pupil.~Quality means in this content that images cover the planned region of interest and images should be sharp and good illuminated to see details for medical reading of retinal findings.~To compare the retinal vessel diameters based on the images of to different camera-systems.~The diameters of arteries and veins are planned to be measured with an automated software algorithm. Are there differences in the calculated results between the two used camera devices?~To detect changes in retinal vessel diameters while pregnancy and after delivery.~Are there detectable changes of the retinal findings between the images taken before and after delivery (e.g. bleeding, edema, vessel tortuosity)
