ABSTRACT It has often been stated that static retinoscopy findings are not affected by the examiner's refractive correction. To what extent this statement remains true is the subject of this paper. The basic principle of retinoscopy is the Foucault test.

Abstract Retinoscopic refraction of an aquatic eye immersed in water is shown to be biased due to refractive effects of the air-water interface between subject and examiner. Ametropias in aquatic eyes are overestimated in retinoscopy by a factor of 1.34 for marine animals and 1.33 for freshwater animals.

Dynamic retinoscopy and accommodation
Ophthalmic and Physiological Optics, 1992The added positive lens power required for low and high neutrals at a distance of 1/3 m is determined as a function of age for a sample of 221 clinically normal subjects, aged between 10 and 80 years. These dynamic retinoscopy results are compared with corresponding laser optometer measurements of the levels of accommodation under each condition.

Retinoscopy and chromatic aberration
Experientia, 1979The origin of the apparent farsightedness as revealed by retinoscopy in smaller eyes was investigated by using monochromatic retinoscopy on wild rabbits. Our results indicate that a combination of long wavelength light and chromatic aberration of the subject's dioptrics is the major source of this artifact.

Retinoscopy was performed on animals with different sized eyes, all of whom appeared hypermetropic. The data were well fitted by an equation of the form y = kx -2 where y is refractive error in diopters, and x is the corneo-retinal ...

Near Retinoscopy and Cycloplegic Retinoscopy in Early Primary Grade Schoolchildren
American journal of optometry and physiological optic, 1979Abstract Retinoscopy under cycloplegia with various agents can yield varied results. Additionally, cycloplegics can produce adverse local as well as central nervous system disturbances. A noncycloplegic near retinoscopy technique as promulgated by Mohindra is compared with cycloplegic retinoscopy on schoolchildren in early grades ...

Comparison of Refraction Obtained by “Near Retinoscopy” and Retinoscopy Under Cycloplegia
Optometry and Vision Science, 1985ABSTRACT This study compared refractive error obtained by the “near retinoscopy” method as described by Mohindra and static retinoscopy under cycloplegic conditions. Twenty‐two patients between the age of 3.6 and 10.0 years were objectively refracted. The examiner performed a near retinoscopy on each patient.

A simple makeshift retinoscopy rack consists of various trial lenses placed into the slots of a nonfrosted, 35-mm slide viewing sheet. It is useful in determining the patient's refractive error at the bedside and in the operating room.
