Abstract:
An apparatus for acquiring, analyzing and displaying images of a retina of an eye using light reflected therefrom, said apparatus comprising:in combination, at least one digital fundus camera and a Retinal Thickness Analyzer (RTA), said digital fundus camera and RTA having common optical components; and a common driving mechanism coupled to simultaneously drive at least one optical component of each of said digital fundus camera and RTA; wherein: said common optical components comprise a common optical combiner unit positioned at a predetermined location for allowing peripheral illumination and centered image acquisition of the eye's fundus by said digital fundus-camera simultaneously with lateral slit illumination and retinal thickness acquisition of the eye by an off-center slit-camera of said RTA; and the common optical combiner unit is a removable dichroic mirror, the dichroic mirror being positionable at said predetermined location for allowing said digital fundus camera to acquire a lower resolution image of the fundus, and being movable out of said predetermined location for allowing said digital fundus camera to acquire a higher resolution image of the fundus.
