Abstract
Disclosed are embodiments of a wide-field fundus imaging system integrating an optical head with multiple radial and central cameras, an illumination system with adjustable LED assemblies, and reflection control elements employing polarized filters to reduce glare. The system includes a handheld imaging device connected to external control and processing units via wired or wireless interfaces, with a disposable coupler for eyelid stabilization during imaging.

A fundus camera comprising:
- a housing configured for handheld operation;
- an optical head disposed at a distal end of the housing, including:
- a camera array including:
- a plurality of radial cameras arranged around a central axis to capture retinal images of an ora serrata region of a patient's eye;
- a central region camera aligned with the central axis to capture a retinal image of a center region of the eye;
- a first plurality of light-emitting diodes (LEDs) assemblies positioned around the center axis and within the optical head, configured to illuminate a field of view of the plurality of radial cameras;
- a second plurality of LED assemblies positioned around the center axis and within the optical head and configured to illuminate the field of view of the central region camera;
- a rigid chassis positioning and supporting the camera array, the first plurality of LED assemblies, and the second plurality of LED assemblies,
- a reflection control system including polarizing filters positioned to reduce glare and reflections;
- a processor positioned within the housing, the processor electronically coupled to the camera array and configured to control image acquisition;
- a user interface component positioned within and on the housing for actuating image capturing from the processor and the camera array;
- and
- a communication interface coupled to the processor for transmitting image data to an external device.

A method of capturing a wide-field image of a retina, comprising:
- positioning a handheld imaging unit adjacent to a patient's eye, the imaging unit comprising a camera array including a center camera and a plurality of radial cameras arranged about a central axis;
- illuminating the patient's eye with an illumination system comprising a plurality of LED assemblies arranged to illuminate respective effective fields of view of the center camera and the radial cameras;
- displaying a real-time video stream from at least one camera of the camera array on an external computing device while positioning the imaging unit;
- and
- determining if a proper alignment has been achieved based on the real-time video stream,
- if proper alignment has been achieved, initiating a capture of a plurality of still images simultaneously from the center camera and each radial camera while the imaging unit is in proper alignment with the patient's eye;
- and
- processing the plurality of still images to generate a composite retina image having a field of view of over 180 degrees.
