Publication number: 20250232446Abstract: Systems and methods are provided herein for minimizing retinal exposure to flash during image gathering for diagnosis. In an embodiment, a system captures a plurality of retinal images of different retinal regions. The system determines that a first portion of a first image does not meet a criterion while a second portion of the first image does meet the criterion, identifies a portion of the retina depicted in the first portion that does not meet the criterion, and determines whether the portion of the retina is depicted in a third portion of a second image and whether the third portion meets the criterion. Responsive to determining that the third portion meets the criterion, the system performs the diagnosis. Responsive to determining that the portion of the retina is not depicted in the second image, the system captures an additional image of the retinal region.Type: ApplicationFiled: April 4, 2025Publication date: July 17, 2025Inventors: Warren James Clarida, Ryan Earl Rohret Amelon, Abhay Shah, Jacob Patrick Suther, Meindert Niemeijer, Michael David Abramoff

Publication number: 20250072752Abstract: Systems and methods are disclosed herein for detecting eye alignment during retinal imaging. In an embodiment, the system receives an infrared stream from an imaging device, the infrared stream showing characteristics of an eye of a patient. The system determines, based on the infrared stream, that the eye is improperly aligned at a first time, and outputs sensory feedback indicative of the improper alignment. The system detects, based on the infrared stream at a second time later than the first time, that the eye is properly aligned, and receives an image of a retina of the properly aligned eye from the imaging device.Type: ApplicationFiled: November 14, 2024Publication date: March 6, 2025Inventors: Warren James Clarida, Ryan Earl Rohret Amelon, Abhay Shah, Jacob Patrick Suther, Meindert Niemeijer, Michael David Abramoff

Publication number: 20240237895Abstract: Systems and methods are disclosed herein for adjusting flash intensity based on retinal pigmentation. In an embodiment, a processor determines a retinal pigmentation of a retina of an eye positioned at an imaging device. The processor commands the imaging device to adjust an intensity of a flash component from a first intensity to a second intensity based on the retinal pigmentation. The processor commands the imaging device to capture an image that is lit by the flash component at the second intensity, and receives the image from the imaging device.Type: ApplicationFiled: March 29, 2024Publication date: July 18, 2024Inventors: Warren James Clarida, Ryan Earl Rohret Amelon, Abhay Shah, Jacob Patrick Suther, Meindert Niemeijer, Michael David Abramoff
