Publication number: 20240363026Abstract: The present invention contemplates an infant eye model for wide field retinal imaging by implementing nominal physical parameters and optical characteristics found in scientific literature and by simulating retinal features and details found in real eye images. The present invention also contemplates implementing a corneal model with a translucent plastic to mimic image haze and 1st Purkinje reflection. The present invention also contemplates implementing a birefringent layer to the lens posterior surface to simulate 4th Purkinje reflection and its brightness variation. The present invention further contemplates implementing a photo-realistic retinal hemisphere shell to provide retinal details and demonstrate retinopathy associated with retinal diseases.Type: ApplicationFiled: July 10, 2024Publication date: October 31, 2024Inventors: Paul A. YATES, Ming LAI, Ta-Wei YI

Publication number: 20240341597Abstract: 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.Type: ApplicationFiled: April 11, 2024Publication date: October 17, 2024Inventors: Paul Andrew YATES, Ming LAI, Ta-Wei YI, Alex MARTINEZ

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
