ABSTRACT
PURPOSE:
To report the results of preschool vision screening in South Korea in 2003.METHODS:
Nation wide, population-based vision screening tests were conducted in preschool children over the age of 3 years from March to September 2003. The first step involved home-screening using picture cards. The children who did not pass the first test were sent to public health care centers, where their visual acuity was re-tested. After the re-tests, some children were referred to ophthalmologists. The referral criteria for visual acuity were age 3, less than 0.5 visual acuity; age 4 or older, less than 0.63 visual acuity in at least one eye.RESULTS:
Among 56,836 subjects who had been enrolled, 2,637 (4.6%) children were referred to ophthalmologists. Refractive error was found in 1,746 (66.2%) children. Amblyopia was discovered in 480 (18.2%) children. Anterior segment abnormalities were detected in 269 (10.2%) children, manifest strabismus was detected in 169 (6.4%) children, and fundus abnormalities were found in 17 (0.6%) children. Myopic astigmatism (31.0%) was the most common type of refractive error. Refractive error (87.9%) was the most common cause of amblyopia and exodeviation (63.9%) was the most common type of strabismus.CONCLUSIONS:
From the results of the 2003 Preschool Vision Screening, we collected data about the ophthalmic abnormalities that can affect visual development in children. This information will foster improvement in the overall quality and design of preschool vision screening systems.
