摘要：
A method of controlling an ophthalmic device operable to image an imaging region of a retina and concurrently illuminate an illumination region of the retina, the method including acquiring a reference retinal image by imaging a reference imaging area of the retina； designating a target in the reference retinal image； acquiring a current retinal image of an initial imaging region within the reference imaging area； moving the imaging region from the initial imaging region to a destination imaging region using the target and the reference retinal image, and acquiring a retinal image of the destination imaging region； illuminating the illumination region while the imaging region is the destination imaging region； acquiring one or more retinal images while the illumination module is being illuminated； and comparing a marker retinal image based on the one or more retinal image(s) with a comparison image based on the reference retinal image.
