1. A method to continuously and consistently monitor an individual's ocular fundus, by enabling an acquisition of standardized fundus images, the method comprising:
(a) using an aiming beam to align and target registration points;
(b) moving an image acquisition unit disposed in an ophthalmoscopic examination instrument to a first test position, wherein the first test position places the individual's fundus in a focal length of the image acquisition unit, and capturing a fundus image;
(c) wherein the image acquisition unit has a ringed target center calculating whether a fundus zone and the ringed target center meet a standard value of overlapping area in a previously established fundus filing image by circling the fundus zone by the ringed target center in the fundus image;
(d) obtaining a standardized fundus image by aligning if a result of the aforementioned step (c) is affirmative; and
(e) moving the image acquisition unit to a second test position by calculating a difference of the fundus filing image if the result of step (c) is negative, and repeating steps (a) to (b) until the fundus filing image meets the standard value of overlapping area,
wherein the standard value of overlapping area is at least 70%.
