An ophthalmoscope handpiece (10) for viewing the fundus oculi and for delivering a laser beam and a laser targeting beam to the fundus. The handpiece (10) comprises a body (26) defining a viewing aperture (32) therethrough. The handpiece (10) is provided with magnifying means, including a magnifying lens (38) mounted in the viewing aperture (32) for providing a magnifyied view of the fundus. An optical fiber coupling assembly (46) connects the handpiece (10) to an optical fiber (50) which communicates a laser targeting beam and a laser beam to the handpiece (10). The coupling assembly (46) is received in a receptor (58) provided in the body (26) such that the targeting beam and the laser beam can be directed into the viewing aperture (32) of the handpiece (10). Beam deflecting means (48), mounted within the viewing aperture (32), serves to intercept the laser beam and targeting beam and redirect the beams out of the viewing aperture (32) such that the beams can be directed to the fundus oculi.
