Full Description
Retinoscopy is an eye exam that determines the refractive error of the eye (long sighted, short sighted, astigmatism). A refraction test indicates the strength of the prescription needed for glasses or contact lenses.This book provides a concise overview of clinical refraction. Presented in an easy to read format, it is divided into two main sections.The first part explains basic clinical procedures for routine refraction, beginning with an introduction to instruments and the procedure, followed by aspects of the test for different disorders including myopia (short sightedness), astigmatism, keratoconus and refraction in children. Section two provides in depth discussion on retinoscopy and correct use of the retinoscope.Key pointsPractical guide to clinical refraction and retinoscopyExplains basic procedures and instruments for refraction testDescribes refraction in different ophthalmic disordersRetinoscopy and correct use of retinoscope covered in depth
