pupillary opening 15 the complete capturing means includes the elements 2 3 4 5 6 8 and 13 herein represented by the digital camera 2 3 and by capturing lens or eyepiece of the mean 13 its afocal complement or means lens 6 optical set of filters 5 and light polarizer 4 which proceed the image acquisition formed by the light reflected on the fundus 16 the camera is constituted by a focal lens 3 which registers the image formed on a ccd image sensor type 2 the optical axis 1 common in both optical means must be adjusted during the measure proceeding in order to approximately coincide with the optical axis of the eye in examination 14 15 and 16 also in the fig1 there are the distances that define the plans of the pupil 15 and the arrangement outlet end of the optical fibers 7 as conjugated distances by actuation of the capturing lens 13 when considered as an integrant element of the lighting means however when considered as an integrant element of the capturing means the capturing lens 13 collects the light that goes out from the pupil 15 and a fundus primary real image 12 is formed between this.
