[Visual acuity study in the child 18 months to 2 years old]
Abstract:
Visual acuity for a child may be determined using objective instrumental methods (especially for children under 18 months) or using clinical examination at the optotype--subjective methods (for children after 18 months). The use of 2 or 3 different optotypes, which are attractive for children, is necessary because of their great capacity of memorizing the tests. The author presents a personal optotype model, with seven different images, which have to be recognized by the children from a distance of 2.5 m.
