  • Patent number: 7290882
    Abstract: A hand held device for examining a patient's retina. In one example, the device generates visible or non-visible illuminating beams having desired spectral content. The illuminating beams are then polarized to generate polarized light beam(s) that are directed towards the patient's retina. At the patient's eye, a portion of the polarized beam is partially reflected by the cornea and travels back to the device, and another portion of the polarized beam enters the eye through the undilated pupil, illuminates the patient's retina, and generates a reflected retinal image (generally de-polarized) which also travels back to the device. The device receives the retinal image and transmits certain portions of the retinal image on through to an image detector (i.e., CCD or CMOS); and the device deflects the received polarized corneal reflections away from the image capture device. Hence, the image capture device receives retinal images but does not receive the polarized corneal reflected light.
