Since then, the features of fundus cameras have improved drastically to include non-mydriatic imaging, electronic illumination control, automated eye alignment, and high-resolution digital image capture. These improvements have helped make modern fundus photography a standard ophthalmic practice for documenting retinal disease. [7]
Currently, Ainnova’s Vision AI software works well with any fundus camera on the market; however, Ainnova and Avant are aiming for exclusivity by developing a lower-cost, easier to use camera that captures retinal images automatically and then uploads those images to the Vision AI software platform, which then produces a “risk report” in ...
Healthy eye fundus viewed through a retinal camera Retinal image with signs of macular degeneration. Teleophthalmology is a branch of telemedicine that delivers eye care through digital medical equipment and telecommunications technology. Today, applications of teleophthalmology encompass access to eye specialists for patients in remote areas ...
A close-up view of the controls of a Topcon retinal camera. A retinal scan is a biometric technique that uses unique patterns on a person's retina blood vessels. It is not to be confused with other ocular-based technologies: iris recognition, commonly called an "iris scan", and eye vein verification that uses scleral veins.
Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before. [4]
A filter is placed in the camera so only the fluorescent, yellow-green light (530 nm) is recorded. The camera may however pick up signals from pseudofluorescence or autofluorescence. In pseudofluorescence, non-fluorescent light is imaged. This occurs when blue light reflected from the retina passes through the filter.
Retinal vessel dynamics have the potential to serve as a tool for the assessment of risks in other organs since they are thought to reflect the general status of the microvasculature (i.e. the smallest vessels in the human body). The value of the examination with the Retinal Vessel Analyzer has been documented in a number of recent studies.
The resolution of the retinal display only (not the camera) is claimed by the manufacturers to be nominally equivalent to 720P. [10] Although "not a medical device" it is hoped that the retinal projection viewer may be of particular value to some visually impaired users, and the adaptation was heavily subsidised by Sony.
