Retinoscopy Medical Test

Retinoscopy is a technique that takes advantage of the eye's natural optics to help determine refractive error. Children's eyes are typically dilated for retinoscopy because the reflex is easier to see when the pupil is large and also because the drops temporarily limit the ability to accommodate or focus. The examiner uses a retinoscope to shine light into the patient's eye and observes the reflection off the patient's retina. Retinoscopy is especially useful in prescribing corrective lenses for patients who are unable to undergo a subjective refraction that requires a judgement and response from the patient. It is also used to evaluate accommodative ability of the eye and detect latent hyperopia. Retinoscopy gives you a starting point for refractometry. Retinoscopy also increases the accuracy, speed, and efficiency of refractometry on any patient with an unknown or questionable refractive error.
