Recent advances in digital photography and 3D monitors has seen some manufacturers incorporating it once again into photographic equipment. [17] [18] The current process involves simultaneously photographing the retina from two slightly different angles. These two images are later used together to create a 3D image.
Teleophthalmology relies on a standard for the representation, storage, and transmission of medical images known as Digital Imaging and Communications in Medicine . The medical imaging standard is managed by the Medical Imaging & Technology Alliance (MITA), which is a division of the Virginia-based National Electrical Manufacturers Association ...
Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. [1] Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina , optic nerve head , blood vessels ...
It is crucial in determining the health of the retina, optic disc, and vitreous humor. [citation needed] The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination).
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.

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.
[18] [19] This has allowed OCTA to obtain detailed images of retinal vasculature in the human retina [20] and become widely used clinically to diagnose a variety of eye diseases, such as age related macular degeneration (AMD), [21] diabetic retinopathy (DR), [22] [23] artery and vein occlusions, and glaucoma.

The vestibulo-ocular reflex is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement in response to neural input from the vestibular system of the inner ear, thus maintaining the image in the centre of the visual field. For example, when the head ...
