Abstract
- Purpose: To investigate the current status of myopia, amblyopia, and strabismus of preschoolers in Taiwan. Methods: The records of a vision screening performed in 2005 at 4 preschools by a tertiary referral medical center in Kaohsiung, Taiwan were reviewed. Cycloplegic refraction, visual acuity by E chart, stereopsis by Titmus and National Taiwan University tests, and ocular alignment were analyzed. Results: Most (97.7%) of the children (n = 618) were able to perform visual acuity testing. There was good correlation between the results of cycloplegic spherical equivalent obtained by autorefraction and by retinoscopy (r = 0.934, p < 0.001). The prevalence of amblyopia was about 5%. A trend was found between amblyopia morbidity and the 4 age groups when a single criterion (best-corrected visual acuity <0.7) was used for all ages (decreased amblyopia incidence with increased age; p = 0.028, χ<superscript>2</superscript> test for trend). The prevalence of myopia was 3.0%, 4.2%, 4.7%, and 12.2% at ages 3, 4, 5, and 6 years, respectively. There was a trend of increased myopia with increased age (p = 0.021, χ<superscript>2</superscript> test for trend). Conclusions: The prevalence of myopia in children ages 3 to 6 years in Taiwan was high compared with the prevalence in other countries. Criteria for amblyopia based on age difference and on the types of visual acuity test are recommended.▪ [Copyright &y& Elsevier]
