Patent number: 11986244Abstract: 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.Type: GrantFiled: January 26, 2021Date of Patent: May 21, 2024Assignee: RETIVUE LLCInventors: Paul Andrew Yates, Ming Lai, Ta-Wei Yi, Alex Martinez

Patent number: 11744460Abstract: 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.Type: GrantFiled: July 2, 2020Date of Patent: September 5, 2023Assignee: Retivue LLCInventors: Paul A. Yates, Ming Lai

Publication number: 20220330817Abstract: Speculums and spacers are used to position a retinal camera to obtain images of a fundus of an eye. In some instances, the speculums and spacers are designed to contact the eye to prevent rotation of the eye during imaging. In other instances, no contact is made with the eye. A light source may include visible light or limited to infrared light.Type: ApplicationFiled: April 18, 2022Publication date: October 20, 2022Applicant: Retivue, LLCInventors: Paul Andrew Yates, Viatcheslav Orlov
