Fundus Camera

This chapter discusses the purpose, principle of operation, specifications, and applications of fundus camera. The fundus camera, also known as retinal camera, is an instrument designed to take photograph of the interior surface of the eye including the retina, optic disc, macula, and, of course, fundus. Modern fundus cameras are nonmydriatic, which are convenient for both the patient and the medical staff. The optical design of the camera is similar to that of the indirect monocular ophthalmoscope because the observation and illumination systems follow dissimilar paths in both the cases. The fundus camera provides an upright, magnified view of the fundus. Fundus photography is different from conventional photography as the object to be photographed is a virtual image of the retina. Fundus cameras are used by optometrists, ophthalmologists, and orthoptists for diagnosis and monitoring the progression of certain eye conditions and diseases.
