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.
AOSLO compares favorably with other retinal imaging techniques as well. Fluorescein angiography uses injection of a fluorescein dye to image the back of the retina. It is a commonly used technique but it has a large number of side effects, including nausea in one fifth of patients and in some cases death from anaphylaxis. [20]
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 ...
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]
[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 Heidelberg Retinal Tomography is a diagnostic procedure used in ophthalmology. The Heidelberg Retina Tomograph (HRT) is an ophthalmological confocal point scanning laser ophthalmoscope [ 1 ] for examining the cornea and certain areas of the retina using different diagnostic modules (HRT retina, HRT cornea, HRT glaucoma).
System: Eye and visual system: Significant diseases: Cataract, retinal disease (including diabetic retinopathy and other types of retinopathy), glaucoma, corneal disease, eyelid and orbital disorders, uveitis, strabismus and disorders of the ocular muscles, ocular neoplasms (malignancies, or cancers, and benign eye tumors), neuro-ophthalmologic disorders (including disorders of the optic nerve)
Retinal birefringence scanning (RBS) is a method for detecting the central fixation of the eye. The method can be used in pediatric ophthalmology for screening purposes. By simultaneously measuring the central fixation of both eyes, small- and large-angle strabismus can be detected. The method is not invasive and requires little cooperation by ...
