The assessment of refractive status in very young children is often not conducted in the same manner as for adult patients. In particular, the child's age, their cooperation and dynamic refractive status will be key factors which influence the accuracy of refraction. For this reason, it is often necessary to choose procedures which inhibit or minimise accommodative activity. This can be achieved by fogging with positive lenses or rousing the tonic (resting) accommodation (dry refraction), or with pharmacological agents (wet refraction). This review article compares the two approaches, focusing on the retinoscopy techniques.
