  • Patent number: 10314486
    Abstract: The present invention is directed to an indirect ophthalmoscopic system for imaging of the ocular fundus including a headband configured to hold a digital imaging device and a plus eyepiece lens in front of an eye of the examiner, with the plus eyepiece lens positioned in between the digital imaging device and the examiner's eye, such that the examiner is focused upon the display of the digital imaging device. The aperture of the digital imaging device receives light reflected from the ocular fundus of the patient's eye, emanating from the patient's pupil. The examiner examines the patient and composes the image of the ocular fundus directly in the display screen. In this way, what the examiner sees is captured by the digital imaging device. Stereoscopic imagery is obtained by optical means that create side-by-side virtual images of the aperture of the digital imaging device within the pupil of the eye.
