Description

Screening is an important public health strategy for disease prevention. It enables the early identification of disease in asymptomatic individuals and allows them to benefit from direct preventive action. (1) Preschool vision screening has been used for the early detection of amblyopia or lazy eye, which is the leading cause of monocular blindness in the 20 to 70 year age group in higher-income countries. (2) Amblyopia is defined as reduced visual acuity (VA) with no obvious structural or pathologic causes that cannot be improved by corrective lenses. (3) The condition develops within the first six years of life, (4) and once established, persists. Many countries have well-established amblyopia screening programs. (5) In Sweden, for example, children beginning at age 4 are assessed for VA by public health nurses in a program that has an uptake of over 99%. (6) Historically, Canadian public health efforts routinely targeted early detection of amblyopia with trained public health nurses, (7) but a 2007 report (8) showed wide variation in amblyopia screening practices among Canadian provinces.
