  • Patent number: 12702297
    Abstract: A wide field fundus camera having multiple illumination beam projectors and to capture multiple retinal images at various viewing angles to facilitate wide field retinal examination. The wide field fundus camera images an entire retina at a single alignment. The wide field fundus camera provides visualization of a retina and Purkinje reflections simultaneously to facilitate alignment. The wide field fundus camera further contemplates narrow and broad slit beam illuminations to enhance autofocusing, imaging through less transparent crystalline lens, and reduction of haze due to reflected and scattered light from camera and ocular surfaces other than the retina. The wide field camera contemplates a real-time algorithm to reduce said reflected and scattered light haze in said retinal images. The wide field camera further contemplates automated montage of said multiple retinal images into a single wide field FOV retinal montage and automated removal reflected and scattered light haze from said retinal montage.

  • Patent number: 11986244
    Abstract: A wide field fundus camera is disclosed to implement multiple illumination beam projectors and to capture multiple retinal images at various viewing angles to facilitate wide field retinal examination. The wide field fundus camera contemplates an ultra-wide field lens that can provide edge to edge imaging of the entire retina at a single alignment. The wide field fundus camera contemplates configuration of said multiple illumination beam projectors to provide visualization of retina and Purkinje reflections simultaneously to facilitate determination of proper camera alignment with the eye. The wide field fundus camera further contemplates control of multiple illumination beam projectors in a programmable manner to further assess alignment of each illumination beam projector with the eye and to capture said multiple retinal images.

  • Patent number: 11744460
    Abstract: A wide field fundus camera is disclosed to implement multiple illumination beam projectors and to capture multiple retinal images at a various viewing angles to mimic wide field retinal examination with an indirect ophthalmoscope. The wide field fundus camera may incorporate a consumer image recording device with fast auto focusing so as to make the device quick to respond and easy to use. The wide field fundus camera may include narrow and broad slit beam illuminations to enhance autofocusing and imaging through less transparent crystalline lens and through haze due to Purkinje reflections from crystalline lens surfaces. Control of multiple illumination beam projectors in a programmable manner can be used to assess alignment of each illumination beam projector with the eye and to capture said multiple retinal images. Furthermore, a method is disclosed to montage said multiple retinal images into a single montage and to remove haze and reflections.
