Abstract

The low light level of the retinoscopic reflex and the small aperture required to obtain the customary shape of the reflex make it difficult to photograph the actual reflex for teaching or permanent recording. We describe the design and application of a television retinoscopy system that solves this problem. The system uses a standard streak retinoscope modified to gather more light, a highly sensitive television camera, and an image processor. The system can be used for live demonstration of retinoscopic techniques or for videotape recordings for teaching or research.
