A fundus camera or retinal camera is a specialized low power microscope with an attached camera designed for fundus photography, that is, creating a photograph of the interior surface of the eye.
Fundus cameras are used for fundus photography, which is used by optometrists, ophthalmologists, and trained medical professionals for monitoring progression of a disease, diagnosis of a disease, or in screening programs, where the photos can be analysed later.
Retinal camera provides for direct, enhanced view of the fundus, and even anterior segment of the eye can be photographed through with it. The camera is affixed to an indirect ophthalmoscope focused at taking picture of the fundus of the eye/the region of the eyeball, opposite the pupil; through the flip mirror/microscope - image focus, clarity of fundus image viewed/photographed is ensured.
Retinal photography is becoming a must in optometric practices. It is not only a tremendous practice builder, but essential in management of the glaucomas. Photographic documentation of diabetic retinopathy patients helps the doctor keep a data base of the progression of the disease, it's on going management and control.
Retinography is a sophisticated means for identifying people by the pattern of blood vessels on the retina. The pattern is so complex that even identical twins do not have the same blood vessel configuration. Those who favor its use claim retinography has an error rate of only one in a million.
"It is compact, fully automated and has a low power flash that helps ensure patients' comfort when they are examined."
