MeSH definition : Instruments for RETINOSCOPY that determines the refractive state of the EYE, such
as the degree of NEARSIGHTEDNESS; FARSIGHTEDNESS; or ASTIGMATISM. In principle, a
retinoscope provides a light source to illuminate the RETINA, and then locates the
aerial image of the retina in space to obtain an index of the refractive quality of
the patient's lens system.;
