Abstract: An eye imager includes a camera having at least one infrared LED. The eye imager captures a sequence of infrared images of an eye using the camera. The eye imager selects an infrared image from the sequence of infrared images. The eye imager determines a cataract is detected in the infrared image and performs an action based on detection of the cataract.

Abstract: A fundus image capture system operates to determine if the system has captured an image that identifies the fundus, a region of interest in the image, or the current field of view. According to the determination, the system can guide the user to operate the system to capture a desired fundus image.

Abstract: A device for monitoring a patient displays a nuisance button on a display device, receives clinician feedback from a selection of the nuisance button, and pauses an active alarm in response to the clinician feedback. The device identifies one or more alarm settings responsible for the clinician feedback and adjusts the one or more alarm settings based on the clinician feedback. The device records the clinician feedback in a device usage log for monitoring usage of the nuisance button. The device generates an alarm notification based on the active alarm, and classifies the alarm notification into a first group in which the alarm notification is a push notification or a second group in which the alarm notification is a pull notification.

Abstract: A fundus imager includes a camera for capturing eye fundus images, and a display for displaying the eye fundus images. The fundus imager captures an eye fundus video using the camera, performs an analysis on the eye fundus video to generate a signal, and calculates one or more vital signs from the signal.

Abstract: A system includes a vision screening device having at least one sensor. The system also includes a controller operably connected to the at least one sensor. The controller is configured to cause the at least one sensor to obtain an image of an eye, and to identify a region of interest associated with a macula of the eye. The controller is also configured to identify drusen disposed proximate the macula, and to generate an augmented image of the eye. The augmented image includes a component indicating the drusen.
