ret·i·nos·co·py (ret″ĭ-nosґkə-pe) [retina + -scopy] an objective method for investigating, diagnosing, and evaluating refractive errors of the eye, by projection of a beam of light into the eye and observation of the movement of the illuminated area on the retina surface and of the refraction by the eye of the emergent rays. Called also skiascopy and skiametry.Medical dictionary. 2011.
