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.

A fundus imager includes a handheld housing that supports a lighting unit configured to illuminate an eye fundus. The lighting unit includes one or more light-emitting diodes. The housing further supports a camera configured to capture one or more images of the eye fundus, and a display configured to display the one or more images of the eye fundus. The fundus imager captures at least one multispectral fundus image using the camera, and displays the at least one multispectral fundus image on the display.

A skin measuring microscope includes a housing, an electronic imager disposed along an imaging axis, and an illumination system. The illumination system includes a plurality of LEDs disposed in a ring-like configuration adjacent a distal end of the housing.

The present disclosure provides methods and an apparatus for imaging and analysing images of presumed protein deposits in the retina, retinal tissue or retinal structures and discloses methods differentiating or classifying these deposits and other optical signals from retinal structures into 1) whether they contain or do not contain classes, of proteins or protein deposits called amyloids or other proteins and/or protein deposits related to neurodegenerative eye and brain disease(s); 2) which type(s) of amyloid or other proteins or protein deposits they contain, as well as 3) whether the form and/or properties of the deposit are associated with a class of diseases or with one or another specific condition(s) (or disease(s)); whether or not this is a disease or class of disease associated with the retina or more generally with the nervous system, including the brain or 4) classified as associated with one or another level of severity of condition(s), or disease(s).

A medical system of an aspect example includes a data acquiring unit and a data processor. The data acquiring unit is configured to acquire data from an eye fundus of a patient using at least one optical method. The data processor is configured to process the data acquired by the data acquiring unit in order to generate information on the circulatory system of the patient.

A method for non-invasive assessment of photoreceptor function in a mammalian subject comprises exposing a subject's eye to a visible light stimulus to initiate an intrinsic reflectance response in one or a population of photoreceptors and capturing multiple images of photoreceptor's intrinsic reflectance response to the stimulus. Patterns of variability in the intrinsic reflectance response of a single photoreceptor or population of photoreceptors are useful in diagnosis and treatment monitoring of an ocular condition, disease, disorder or a response to treatment for said ocular condition, disease or disorder.
