Population
This project is a population-based survey of refraction and other eye conditions in school children predominantly 12 years of age, resident in the metropolitan area of Sydney, Australia. It forms part of the Sydney Childhood Eye Study, which is examining childhood eye conditions across a range of ages.20, 21, 22, 23 Methods used to identify and select the target sample, as well as a description of study procedures, have been reported.24 In brief, all secondary schools in the study area were
Subjects
Of 3,144 eligible children, 2367 children were given parental permission to participate and questionnaire data were provided by the parents (response rate 75.3%). Of these 2,367 children, 14 were not examined as they were absent during the examination period. The mean age of participants was 12.7 years: 69.9% were aged 12 years and 25.6% were aged 13 years. The majority of the remainder were aged 11 years; 49.4% were girls. Basic data on the distribution of age and ethnicity for study
Discussion
To our knowledge, very few population-based studies have documented the prevalence of reduced stereopsis in representative samples of children. Williams et al reported stereoacuity findings on a representative childhood sample aged 7 years, living in Dunedin, New Zealand; these children were reexamined at ages 9 and 11 years.17 Defective stereopsis was defined as failure to pass any of the TNO qualitative plates and was found in 2.3% of the sample at age 11 years. Application of our criterion
