Claim 5:
6. An ophthalmoscopic examination device for acquiring standardized fundus images to continuously and consistently monitor ocular fundus, comprising:
an image acquisition unit, for capturing an image to be identified, wherein the image to be identified is a standardized fundus image in a focal length of an image acquisition unit;
an individual fundus image database, for storing a fundus filing image, wherein the fundus filing image uses the Fovea and Optic cup of fundus of an individual as two registration points;
a display unit, electrically connected to the image acquisition unit and the individual fundus image database, with a ringed target center displayed and transmitted from the image acquisition unit, wherein a fundus zone is circled in the fundus image;
a feature recognition matching unit, electrically connected to the display unit, wherein the feature recognition matching unit calculates whether the fundus zone and the fundus filing image meet a standard value of overlapping area, wherein the standard value of overlapping area is at least 70%, if not, the instrument provides an error message,
wherein the device sends the error message, then is moved to a second test position after calculating difference of the fundus filing image.
