Color Fundus Photography
The color fundus photography is a diagnostic procedure that involves the use of a device known as a fundus camera to record colored images of the interior surface of the eye. The goal of this procedure is to monitor the presence of disorders and their change with time. The fundus camera (which is used for this procedure) is similar to a microscope with a camera that can photograph the interior of the eye. Structures of the eye that are captured in fundus photos include the retina, optic disc, macula, blood vessels of the retina and the posterior pole (i.e. the fundus).
First, the pupil of the eye must be well-dilated before the photography can be performed. This allows the camera to capture the best possible images of the eye by allowing light into the eye. The pupil naturally constricts against bright light (which is a feature of the fundus camera). After dilation, you will then stare intently at a fixed point to help keep your eyes still. You will then experience a series of bright flashes as photographs are taken.
Color fundus photography monitors conditions such as diabetic retinopathy, age-related macular degeneration, macular edema, glaucoma, color vision deficiencies, problems with the optic nerve, and retinal detachment.
The procedure helps to map each eye’s individual life cycle and developing health. Because of the powerful imaging, it provides a bird’s eye-view of the innermost layers of the retina. It can also be used to monitor the progression of diseases over time, allowing for better treatment plans.
