Abstract
A scanning ophthalmoscope for repeatedly scanning a selected portion of an eye fundus has a laser source which produces a directed narrow-beam output and means for scanning the fundus with at least one selected scanning sequence. The scanning beam passes through a pivot point located in a preselected plane, preferably within the eye, for providing a wide field of view. An optical system directs light reflected from the fundus to a detector, which produces an electrical output signal proportional to the detected light. An output element provides a visual representation of the magnitude of the output signal in a spatial distribution corresponding to the scanning sequence.
