Digital Retinal Imaging (DRI) is an accurate and painless way for your eye doctor to examine the structures inside your eye and track changes to your ocular health and vision.
Digital retinal imaging, also known as a retinal photograph, is a non-invasive, diagnostic tool that produces digital high resolution, colored images of your retina, optic nerve, and blood vessels inside your eye.
The DRI is now commonly performed as part of your regular eye exam. However, if you notice any changes to your vision, or vision loss, your eye doctor may wish to use a DRI test to rule out any ocular diseases that may be damaging your retina. Additionally, if you have been diagnosed with any of the following conditions, your eye doctor may recommend a DRI test:
Corneal topography, also known as corneal mapping, is a diagnostic tool that provides 3-D images of the cornea.
Corneal topography is a computerized test that generates a three-dimensional image of the surface of the cornea, the outer and front-most layer of the eye. A corneal topography test provides detailed 3D maps of the cornea’s shape and curvature and enables detection and monitoring of corneal diseases, and irregular corneal conditions, such as swelling, scarring, abrasions, deformities and irregular astigmatism.
The purpose of a visual field test, often called a perimetry exam, is to detect changes in peripheral vision. The visual field exam is a crucial part of glaucoma diagnosis and is repeated periodically to determine if the disease is stable or getting worse.
Some people with glaucoma do not notice any problems with their vision, but the visual field test shows that peripheral vision is being lost.
A visual field test can also help the doctor find out more about the part of the nervous system that allows us to see. The visual part of the nervous system includes the retina (the "film" in the camera-like eye), the optic nerve (the "wire" that carries images from the retina to the brain), and the brain itself. Problems with any part of this system can change the visual field. There are well-known patterns in the test results that help doctors recognize certain types of injury or disease. By repeating more visual field tests at regular intervals, doctors can also tell whether the patient is getting better or worse.
