Claim One:
1 .- 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.
