Uncorrected Hyperopia and Preschool Early Literacy: Results of the Vision in Preschoolers-Hyperopia in Preschoolers (VIP-HIP) Study.

ABSTRACT:

Purpose

To compare early literacy of 4- and 5-year-old uncorrected hyperopic children with that of emmetropic children.

Design

Cross-sectional.

Participants

Children attending preschool or kindergarten who had not previously worn refractive correction.

Methods

Cycloplegic refraction was used to identify hyperopia (≥3.0 to ≤6.0 diopters [D] in most hyperopic meridian of at least 1 eye, astigmatism ≤1.5 D, anisometropia ≤1.0 D) or emmetropia (hyperopia ≤1.0 D; astigmatism, anisometropia, and myopia <1.0 D). Threshold visual acuity (VA) and cover testing ruled out amblyopia or strabismus. Accommodative response, binocular near VA, and near stereoacuity were measured.

Main outcome measures

Trained examiners administered the Test of Preschool Early Literacy (
