RETINAL IMAGING SYSTEM

Provided is a wearable fundus camera configured to be worn as a headset by a human, the wearable fundus camera comprising: an infrared light source configured to output infrared light to be directed at a retina of the human; an image sensor configured to capture infrared images depicting a retina of an eye of the human under illumination from the infrared light source without a pupil of the eye being dilated with mydriatics; and an eye cuff configured to be biased against a face of the human and occlude at least some ambient light from reaching the image sensor.

HAND-HELD PORTABLE FUNDUS CAMERA FOR SCREENING PHOTOGRAPHY
20220071486 · 2022-03-10 ·

System and Method pertaining to the modification and integration of an existing consumer digital camera, for example, with an optical imaging module to enable point and shoot fundus photography of the eye. The auto-focus macro capability of existing consumer cameras is adapted to photograph the retina over an extended diopter range, eliminating the need for manual diopter focus adjustment. The thru-the-lens (TTL) auto-exposure flash capability of existing consumer cameras is adapted to photograph the retina with automatic flash exposure eliminating the need for manual flash adjustment. The consumer camera imaging sensor and flash are modified to allow the camera sensor to perform both non-mydriatic focusing of the retina using infrared illumination and standard color flash photography of the retina without the need for additional imaging sensors or mechanical filters. These modifications and integration of existing consumer cameras for fundus photography of the eye significantly improve ease of manufacture and usability.

Self-Illuminated Handheld Lens for Retinal Examination and Photography and Related Method thereof

System and method directed towards providing full and even illumination of a patient's retina through lighting integrated into a handheld fundus lens. By integrating the lighting, the method and system reduces and even eliminate many lens artifacts and reflections. By increasing the accuracy, quality, and field of view afforded during clinical examination of the retina, the method and system will allow practitioners to make more accurate diagnoses and will increase safety during retinal surgical procedures.

Ophthalmic machine for acquiring fluorescence images of the retina and related method of use

An ophthalmic machine is provided for obtaining and diagnosing fluorescence images of the retina. An excitation light having first wavelengths (e.g., between 430 nm and 490 nm) is scanned onto the retina. Light emitted by the retina, when illuminated thereby, is filtered to block light of the first wavelengths and to pass light of second (higher) wavelengths. A second filter selects a component of the passed light having second (e.g., green) wavelengths, and a third filter selects a component of the passed light having third (e.g., red) wavelengths. First and second detection means receive light transmitted by the first and second filters, respectively, and provide detection signals indicative thereof. The detection signals are processed to provide one or more images of the retina, said images of the retina comprising at least a color fluorescence image of the retina.

Medical interfaces and other medical devices, systems, and methods for performing eye exams

A mask for performing an eye exam of a subject includes one or more optically transparent sections for transmitting an incident light beam therethrough and incident on the subject's eye, in some embodiments, the one or more optically transparent sections are coated with an anti-reflective coating configured to reduce reflection of the incident light beam by the one or more optically transparent sections. In some embodiments, the one or more optically transparent sections may have a portion thereof that is tilted with respect to the incident light beam when the mask is optically interfaced with the docking portion of an ophthalmic instrument, such that the incident light beam forms a finite angle of incidence with respect to the corresponding portion of the optically transparent sections.

PERSONALIZED PATIENT INTERFACE FOR OPHTHALMIC DEVICES

A medical ophthalmic system uses a patient-specific face mask to establish a predefined alignment between the ophthalmic system and an eye of a patient. The patient-specific face mask may optionally provide a light proof enclosure for the eye. The face mask may be coupled directly to an ophthalmic device, or its housing/enclosure, of the ophthalmic system. The face mask may be 3D printed based on a 3D model of the patient's face.
