Abstract
A macula-disc camera records the first aerial image of the patient's fundus to provide an actual increase in resolution of retinal detail not obtainable by merely magnifying this image with the recording optics. An array of optical fibers surrounds the contact lens to illuminate a limied field of the fundus, on the order of 18.degree.. A high degree of contrast is achieved by tightly separating the observation and illumination beams throughout the lens of the cornea and crystalline lens. Magnification, is on the order of 6.8 times.
