Abstract

The optics of retinoscopy can be understood from a consideration of an important fact. That fact is that the retinoscopist views the eye through a sighthole which is not coincident with the source. In this context the optics of retinoscopy can be analyzed using a format similar to that previously conducted for eccentric photorefraction^1,2 where patterns of light observed in the plane of the pupil are found to be a function of the eccentricity of the source. The fundamental difference in the techniques is in the variability of the source position and the small sighthole aperture employed in retinoscopy.
