Portable fundus viewing system for an undilated eye

摘要

The system of the present invention allows the fundus of an undilated eye to be viewed extremely easily and without the need for the viewer to align a hand held unit with a head mounted unit. The system for viewing the fundus of an undilated eye in accordance with the present invention includes a number of point sources of light that are individually actuable and arranged in a linear array. A lens converts each point of light to a line of light. The point sources of light are sequentially actuated, i.e. turned on and off in sequence, so as to scan the fundus of the undilated eye with lines of light that are directed from the lens to the eye by an optical system. The optical system directs light reflected from the fundus to an image generating apparatus that is responsive to the reflected light to provide an image of the fundus that can be viewed.
