Abstract
A wide-angle indirect ophthalmoscope that enables an operator to view the retina from the posterior pole to the equator as a single image. The ophthalmoscope has an observable field that can include the entire retina. The ophthalmoscope includes optical fibers built into a contact lens in a circular pattern. The fibers are connected to a light source to illuminate the retina, and the contact lens is utilized for observation. The fibers are maintained in a pre-determined fixed orientation in the lens to produce uniform illumination over the entire retina.
