Digital Retinography – Diabetes Assessment and Management Clinics

Blausen_0312_DiabeticRetinopathy

Digital retinography also known as fundus photography is the creation of a photograph of the interior surface of the eye, including the retina, optic disc, macula, and posterior pole. Fundus photography is used by optometrists, ophthalmologists, and trained medical professionals for monitoring progression of a disease, diagnosis of a disease (combined with retinal angiography), or in screening programs and epidemiology.

Fundus photography has the advantage of allowing the image to be examined by a specialist at another location or at another time, as well as providing photo documentation for future reference.

Modern fundus photographs generally recreate considerably larger areas of the fundus than what can be seen at any one time with handheld ophthalmoscopes. Digital retinography is a valuable screening tool for assessing diabetic retinopathy or growth of new blood vessels due to poorly controlled blood glucose.

In patients with diabetes mellitus, regular fundus examinations (once every 6 months to 1 year) are important to screen for diabetic retinopathy as visual loss due to diabetes can be prevented by retinal laser treatment if retinopathy is spotted early. Digital retinography does not take the place of a comprehensive eye exam by a trained eye care provider.
