Analysis of Ophthalmic Examination for 4 and 5 Year Old Children Referred from Previous Vision Screening

ABSTRACT

We performed comprehensive ophthalmic examinations for 127 children at 4 and 5-year-old referred from primary(for 3315 subjects) and secondary(for 1441 subjects) vision screening. Although it may be duplicated, the 112 children(3.4%) had ametropic eyes, 49(1.5%) amblyopia, and 8(0.2%) strabismus. The mixed astigmatism took possession of 40% of ametropia, and 93.2% of ametropia had astigmatism on the whole. Among strabismic children, the case of exotropia was equal to that of esotropia by 4. The Titmus and TNO stereoacuity were not adequate to detect amblyopia. The early detection of eye problems for preschool children is important to prevent the permanent visual disability. It is necessary to make institutional devices for preschool vision screening.
