Theory of eccentric photorefraction (photoretinoscopy): astigmatic eyes

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 1991
An optical analysis of eccentric photorefraction (photoretinoscopy) of astigmatic eyes is presented. The size and the angular tilt of the dark crescent appearing in the subject's pupil are derived as a function of five variables: the ametropia of the eye (Dsph, Dcyl, axis), the eccentricity of the flash, e, and the distance of the camera from the ...

Optics of Photoretinoscopy

Optometry and Vision Science, 1985
ABSTRACT Recent photographic studies have generated mewed interest in the optics of the retinoscopic (skiascopic) image. In photoretinoscopy the subject's eye is illuminated by a point source of light and the fundal image of this light at the plane of the subject's pupil is observed or photographed from a position near the source.
