Abstract: Embodiments of the present disclosure disclose a method and a computing unit for imaging of wider angle fundus of an eye of a subject. The method discloses guiding placement of an imaging device at set of predetermined locations on the eye. The method further comprises receiving set of images of the fundus of the eye upon determining the imaging device to be at least one of the set of predetermined locations, wherein the set of images are captured by the imaging device upon receiving instructions from the computing unit. The method further comprises determining quality of the set of images and concatenating the one or more images to provide a wider angle target image of the fundus of the eye.

Abstract: Embodiments of the present disclosure provides an illumination device (300), comprises of one or more sources (301) which provides light arranged in a predefined configuration and a collar (303) with a first end (304) and a second end (305) to guide light received at the first end towards the second end. The collar guides the light in a medium between an internal wall and an external wall of the collar by reflection. The light from the second end is used to illuminate a target area for an imaging device. The method of illuminating a target area by an illumination device comprises of powering one or more sources to provide light for illumination and guiding the light in the medium to illuminate on the target area.
