Abstract

A portable diagnostic image analysis instrument for retinal funduscopy in which an eye fundus image is optically processed by a lens system (24) to a CCD device (32) which produces recordable and viewable output data and is simultaneously viewable on an electronic view finder 36. The fundus image is processed to develop a representation of the vessel or vessels from the output data.
