    摘要： The present invention is related to a system for obtaining a fundus image, constituted by optical means implemented in an equipment to observe and photograph the image of the wall fundus (16), comprising a capturing optical means composed by high sensibility digital camera, constituted by an image sensor (2) and focal optical system (3), said digital camera being used to register a captured image by an afocal optical system, composed by a capturing lens (13) and its afocal complement (6); a lighting optical means provided from a arrangement conformed with optical fiber bundle (7), (8), (9) and (10), halogen light source (23) or light emitting diode source (LED); wherein said light beam from the halogen light (23) or light emitting diodes has an annular form when it pass in the anterior part of eyeball (14) and focus in the pupil plan (15); both the means having the optical path partially common over the optical axle (1) from the optical fibers arrangement (7), (8), (9) and (10) to the fundus (16), region in that both the beams are coaxial; in that both the optical means are equipped with light polarizers (4) and (11), being integrated with mechanical, electronics and computerized components, and applicative program, which allow control the equipment and its multiple operational configurations, conducing image acquisition and processing, and displaying the results.
